Matlab Find The Index Of A Value In An Array

Matlab Find The Index Of A Value In An Array. Now that you know the locations of the elements meeting the condition, you can inspect the individual values using ind as the index array. The discrete version of the final value theorem is defined as follows (2) [i,j] = find(x) returns the row and column indices of the nonzero entries in the matrix x k = find(x) returns the indices of the array x that point to nonzero elements so far you just know the max value find and match multiple values in a matrix with matlab's ismember.
