how to stop variable auto display in command window

Hi everybody,

everytime I create a variable (ie a = zeros(n,n,n)) and do operation on the matrix created like a :

for i=1:n
   a(i,0,0) = log(tmp(i) / tmp(i-1);
end

the matrix is being displayed in the command window (in the for loop, matrix being displayed n times). I would like to stop that but I cannot find how. I would like the command window to display only the variables I am asking it to display via the disp function.

Anyone ?

PS : if there any shortcut that perfom the for loop ?

Add a semicolon to the end of the lines that update variables. This will tell the command window to skip displaying these variable changes. Super helpful for debugging in iteration since you can choose which variables display updates line by line!

As your example code does not run at all (brackets unbalanced, zero indices), I am not sure if your real code uses the semicolon. The semicolon supresses the output.

sorry I improvised it to simplify it (code much more complex), good code looks like

for i=1:n
   a(i,1,1) = log(tmp(i) / tmp(i-1));
end

The idea is that every change in a cell of 'a' implies a full display of the 'a' matrix in the command window which I don't want.

Nothing is displayed in the command window, if you run the posted code.
