Modify mySolve. m to make sure the inputs are valid. Your function should check for each of the following cases: 1. A is not a square matrix; 2. b is not a column vector; 3. Ax and b do not have the same dimension. Submit your m-file and a diary showing how you tested the code. Only submit the m-file for mySolve. m. Do not submit the m-files for backward. m, forward. m, or MYLU. m. Test to show that each error code works and that the program still works using the follow tests.1) To test the error of A not being a square matrix use A = (1 2 3 4 5 6), b = (1 2 3). 2) To test the error of b not being a column vector use A = (1 2 3 4), b = (1 2). 3) To test the error of Ax and b not having compatible dimensions use A = (1 2 3 4), b = (1 2 3 4). 4) To test that the program still works given no errors use A = (1 2 3 4), b = (1 2). Then make sure that Ax = b.

4.11 painting a wall (1) prompt the user to input integers for a wall's height and width. calculate and output the wall's area (integer). note that in this case there is a new line after each prompt. (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

Write a program in plp assembly that counts up by one starting from zero (or one) inside a loop and writes this value to the leds every time the value is increased. the memory address of the leds is 0xf0200000. the table below shows the meaning and an example usage of the instructions covered in the video, plp instructions for project 1. instruction example usage meaning load immediate li $t0, 8 register $t0 is set to the value, 8. store word sw $t2, 0($t1) the value in register $t1 is used as the memory address. the value in register $t2 is copied into this memory address. add addiu $t4, $t3, 29 register $t4 is assigned the sum of 29 and the value in register $t3. jump j your_label_name the program jumps to the line following the label, "your_label_name: ". label your label name: defines a label called "your_label_name: " that can be jumped to
