but sir, kafa=(a-b).^2 has again that probelm. Error using - Matrix dimensions must agree.

Error in prctc (line 3) kafa=(a-b).^2

One way:

B=reshape(B,30,15);
A./B

What do you plan to achieve by this?

(1:A-1:B)

if i do kafa=(1:a./1:b). now it is giving me the result but it doesnot give me the plot. kafa versus pt while kafa is 1x3812 after the calculation of kafa=(1:a./1:b) but on the other hand pt is 1x450. but if i do the same method with kafa plot versus pt...plot(1:pt,1:kafa)...or plot(pt,kafa) then it doesnot give me the plot and it gives an error that Vectors must be the same lengths.
