if i have two matrices A and B. the matrix A combination is 1x15 while matrix two combination is 1x450 and i wanna divide A by B but the dimensions are not equal.so how can i solve this probelm?

kafa=(A-B).^2

[waqas muhammad]

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

[waqas muhammad]

i use this method...kafa=(1:A-1:B). it works but it gives the result and the result is an empty bracket.

[Birdman]

What do you plan to achieve by this?

(1:A-1:B)

[waqas muhammad]

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.
