Return index of value matlab

I'm trying to write a script in MATLAB that finds the location of the minimum value of a 2D array of numbers. I am certain there is only 1 minimum in this array, so having multiple locations in the array with the same minimum value is not an issue. MATLAB - multiple return values from a function?

Indices to nonzero elements, returned as a vector. If X is a row vector, then k is also a row vector. Otherwise, k is a column vector. k is an empty array when X is an empty array or has no nonzero elements. You can return the nonzero values in X using X(k). I'm trying to write a script in MATLAB that finds the location of the minimum value of a 2D array of numbers. I am certain there is only 1 minimum in this array, so having multiple locations in the array with the same minimum value is not an issue. Oct 07,  · How do I find the indices of the maximum (or minimum) value of my matrix? Asked by MathWorks Support Team. MathWorks Support Team The "min" and "max" functions in MATLAB return the index of the minimum and maximum values, respectively, as an optional second output argument. is index of the minimum value. Similarly it works for the max 1. Sep 22,  · The first code returns match-Array with [4][][]. Why 4 and not 5, since "5" has the linear indexing 5 in the first cell Array?" Actually the code is correct, and 4 is the linear index of the value 5. M = max(A) returns the maximum elements of an array. If A is a vector, then max(A) returns the maximum of A. If A is a matrix, then max(A) is a row vector containing the maximum value of each column. If A is a multidimensional array, then max(A) operates along the first array dimension whose size does not equal 1, treating the elements as vectors. The resulting matrix has values of logical 1 (true) in place of the NaN values, and logical 0 (false) in place of the 10s. The logical NOT operation, ~A, converts the numeric array into a logical array such that A&C returns a matrix of logical 0 (false) values and A|C returns a matrix of logical 1 (true) values. Many MATLAB functions that start with is return logical arrays and are very useful for logical indexing. For example, you could replace all the NaN elements in an array with another value by using a combination of isnan, logical indexing, and scalar expansion. To replace all NaN elements of the matrix B with zero, use. MATLAB - multiple return values from a function? How can I index a MATLAB array returned by a function without first assigning it to a local variable? How to get the return value from matlab in bash script? 2. Make a function return multiple values in Matlab. value = magic(5)(3,3); value = (magic(5))(3,3); to dispense with the intermediate variable. However, MATLAB complains about Unbalanced or unexpected parenthesis or . Description. return forces MATLAB ® to return control to the invoking function before it reaches the end of the function. The invoking function is the function that calls the script or function containing the call to return. If you call the function or script that contains return directly, there is no invoking function. View MATLAB Command Find the nonzero elements in a 4-byby-3 array. Specify two outputs, row and col, to return the row and column subscripts of the nonzero elements. When the input is a multidimensional array (N > 2), find returns col as a linear index over the N-1 trailing dimensions of X. Sep 22,  · Actually the code is correct, and 4 is the linear index of the value 5. This is the whole array and its corresponding linear indices: >> [1,2,3;4,5,6] % your matrix. Oct 07,  · The "min" and "max" functions in MATLAB return the index of the minimum and maximum values, respectively, as an optional second output argument. For example, the following code produces a row vector 'M' that contains the maximum value of each column of 'A', which is 3 for the first column and 4 for the second column. cat-research.com(5) I realized this function, using for loop and if statement, but did Matlab doesn't have build-in similar function? 0 Comments.

Ask Question Asked 4 years, 11 months ago. Active 4 years, 11 months ago. Viewed times I would like to extract index value from indexed image from specific coordinate (X, Y) in Matlab. I have used.k = find(X) returns a vector containing the linear indices of each nonzero element in array X. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. [row,col,v] = find(___) also returns vector v, which contains the nonzero elements. I know, that number, for example, 5, is an element in array X, but I don't know it's index. In Python, I can use: cat-research.com(5). I realized this function. The "min" and "max" functions in MATLAB return the index of the minimum and maximum values, respectively, as an optional second output argument. I have a cell array of the form: A={[1,2,3;4,5,6],[11,22],[33;55;66;7]}; Now I want the code to return the index of e.g. value "5", i.e. A{:1}(2,2). Each value in B represents a logical 1 (true) or logical 0 (false) state to Use the find function to get the index of the element equal to 8 that satisfies the. find. Find indices and values of nonzero elements. Syntax. indices = find(X) indices = find(X, k) indices = find(X, k, 'first') indices = find(X, k, 'last') [i, j] = find. The function is max. To obtain the first maximum value you should do [val, idx] = max(a);. val is the maximum value and idx is its index. find. Find indices and values of nonzero elements. Syntax. k = find(x) [i, j] = find(X ) [i, j, v] = find(X). Description. k = find(X) returns the indices of the array X that. Another great difference between Scilab and Matlab is that Matlab returns column vectors of indices when X is a column vector or a matrix but Scilab always . C = UNIQUE(A) for the array A returns the same values as in A but with. % no repetitions. [C,IA,IC] = UNIQUE(A) also returns index vectors IA and IC such that. - Use return index of value matlab and enjoy Find indices and values of nonzero elements - MATLAB find
