Using MATLAB

Write an m-file that determines the row and column indices for all non-zero elements in a matrix, x. Row indices should be stored to the variable i, and column indices should be stored to the variable j. For the purpose of testing and grading your m-file: DO NOT issue a clear command at the start of your m-file DO NOT define the matrix x within your m-file. That vector should exist in the workspace prior to executing your m-file. Do not display i and j. This will be done by the script the grader uses to test your m-file. Variable names (x, i, and j) must be exactly as specified (lower case)
