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

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)
