Hi, i have this problem: Let A_ij =ij-j^2 for all i,j {1.2...10}
Im using this for loop:
for i=1:10
for j=1:10
A(i,j)=i*j-j^2
end
end
However I need to find a way to do the for loop without displaying the result each step. In other words, find the execute but don't display output syntax.
I don't know how to do it.

Such basic details are explained in the Getting Started chapters of the doucmentation. You cannot use such a powerful tool as Matlab without reading the documentation.

for i=1:10
for j=1:10
A(i,j)=i*j-j^2;
end
end
Use semicolon at the end of the statements to suppress the output

Use ';' at the end of a statement. It suppresses the display of output on the command window.
In your case
A(i,j)=i*j-j^2;
Refer Link for more information.

FYI, this wasn't available when the question was originally asked but as of release R2024b you can tell MATLAB to stop whenever a command would display unsuppressed output. This lets you locate missing semicolons in a potentially long segment of code. The Editor will let you specify you want to "Pause on Unsuppresed Output" (see the "Error Breakpoints" section on this documentation page) if you prefer using the graphical interface to using the command-line debugging tools.
