How can I multiply matrix with multiple vectors without loop?

I have a matrix R of size 3by3 and vector matrix T (multiple vectors) as illustrated in Figure. How can I get the output as I shown in the figure. I don't

want to use the loop.

Hello K M, You do this exactly as you have written it.

T = [T1 T2 T3 .... Tn];      % concatenate as many 3x1 column vectors as you would like.
Output = R*T;                % 3xn matrix

Then the column vector R*Tj is Output(:,j), the jth column of Output.
