Matlab

1. Write a for loop over the index i. This for loop will execute a piece of code for 20 times, each time producing an array of 100 random numbers and storing it in a new variable called variable_i. As a result, when the for loop is finished running, there should be 20 variables stored in your workspace named variable_1 to variable_20 each containing 100 random numbers. (Take a screenshot of your code and a screenshot of your workspace showing the 20 variables in your workspace.)

2. Create a matrix of size 100x20 and call it A. Fill the columns of A with the 20 variables (variable_1, , variable_20).
