I have the following 3 sets of files in .mat format
X1
X2
X3 ......

I loaded all of them and i want to do the following
t1=X1(:,2)./1000;
t2=X2(:,2)./1000;
t3=X3(:,2)./1000;

x1=-X1(:,4)*0.001;
x2=-X2(:,4)*0.001;
x3=-X3(:,4)*0.001;

tr11=t1-(x1./vr);
tr21=t2-(x2./vr);
tr31=t3-(x3./vr);

can some one help me how to do it when i have 100's of files.
Thank you in anticipation
cheers

Don't load them into variables like that. See the Matlab FAQ 4.6:
http://matlabwiki.mathworks.com/MATLAB_FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F

When you load your files into a cell array, then you can use a for
loop to go through and process each cell as you do above. (Note: Use
{} (braces) to get the value within a certain cell)
