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)

this does not make any sense.. i you can reword that i can maybe you

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
