Uniform Interpolation/resample Question

Please find the attachment data.mat
figure(1)
plot(exp_f2,exp_t2,'ro')
ylabel('Unifrom Time Step 2.5ms');xlabel('Hz');title('Mode 2 Exp data,fs=400Hz')
Here I have uniform time step 2.5ms on my y axis. But I need an uniform frequency step on my x axis like
f2_interp=linspace(exp_f2(1),exp_f2(end),400);
How can I interpolate or resample it? Thanks!

% interpolation
ti=linspace(min(exp_t2),max(exp_t2),400);
yi = interp1(exp_t2,exp_f2,ti) ;
plot(yi,ti)

Now I'm really confused. You want to make a variable uniform that is already uniform? And if you already have the code to do that, what is your question? And to what code are you referring to as "your code"? I haven't posted any code in this thread, only you and KSSV have.
