AI Thread Summary
To calculate the product of elements in a vector in MATLAB (R2010a), use the command p = prod(f), where f is the defined vector. For a 4D matrix M with dimensions a * b * c * n, element-wise multiplication can be achieved using M(:,:,:,1).*M(:,:,:,2).*...*M(:,:,:,n). To perform the product over a specific dimension, refer to MATLAB's Help documentation for guidance. The community encourages users to seek help but also emphasizes the importance of independent learning. Understanding these functions is essential for effective MATLAB usage.

Can someone tell me how to do the following in MATLAB (R2010a):

f(1)*f(2)*...*f(n)

thanx in advance.

I assume that you have already defined the contents of the vector f of length n.
Then
p = prod(f);
 
Hi, marcusl

I have a 4d matrix M, with size: a * b * c * n
This is exactly what I want: M(:,:,:,1).*M(:,:,:,2).*...*M(:,:,:,n) (this is element wise multiplication of the elements)

Please help.
 
Read Matlab's Help entry, which tells you exactly how to take the product over a desired dimension (index). I will help you if you're stuck, but I will not do all your work for you.
