How to use operations in for loop problems

For values of 1 to 60, create a for-loop that does the following. If the value is 1 to 20, have

the operation be number2, if the value is 21 to 40, have the operation be number, and if the

value is 41 to 60, have the operation be √number. Store all 60 results in 3 different variables

that start at 1. With the results, create a 3x20 matrix where the first row is the results of the

first operation, the second row being the results of the second operation, and the final row

being the results of the final operation

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free MATLAB Onramp tutorial to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

For this task, you can use for loop as follows

A = zeros(3,20);
for ii = 1:60
    if ii<=20
        A(1,ii) = ii^2; %first operation
    elseif ii<=40
        A(2,ii-20) = ii; %second operation
    else
        A(3,ii-40) = sqrt(ii); %third operation
    end
end

disp(A)
