Thank so much! It worked

How do I solve the matrix created

@AFARIEBOR, exactly what does that mean? A matrix is just an array of numbers. Exactly what does "solve" mean to you? Explain it in a new question, after you read this: TUTORIAL: How to ask a question (on Answers) and get a fast answer

Alternatively (since you already have a solution to your homework problem from the other Answer) you can do
m = 10 * rand(10); % Floating point/fractional numbers between 0 and 10
m(1,:) = 1; % Set first (top) row to all 1's.
m(:, 1) = 1 % Set first (left) column to all 1's
m = 10×10
