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)

(submit for 1 point). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet (2) extend to also calculate and output the amount of paint in gallons needed to paint the wall (floating point). assume a gallon of paint covers 350 square feet. store this value in a variable. output the amount of paint needed using the %f conversion specifier. (submit for 2 points, so 3 points total). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet paint needed: 0.471429 gallons (3) extend to also calculate and output the number of 1 gallon cans needed to paint the wall. hint: use a math function to round up to the nearest gallon. (submit for 2 points, so 5 points total). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet paint needed: 0.471429 gallons
