Learn How to Calculate Product in MATLAB (R2010a) | Step-by-Step Guide

[dunyali]

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.

Hello there,

Calculating the product of a series of numbers in MATLAB (R2010a) is a simple task. You can use the 'prod' function to achieve this. Here's a step-by-step guide on how to do it:

1. First, create a vector with the numbers you want to multiply. Let's call this vector 'f'. For example, if you want to calculate the product of 1, 2, and 3, your vector would be: f = [1, 2, 3].

2. Next, use the 'prod' function to calculate the product. Simply type 'prod(f)' and hit enter. This will return the product of all the numbers in the vector 'f'.

3. If you want to calculate the product of a larger series of numbers, you can use a for loop to iterate through the numbers and update the product at each iteration. Here's an example:

product = 1; % initialize product variable
for i = 1:n % n is the number of elements in your vector
product = product * f(i); % multiply product by each element in the vector
end
disp(product); % display the final product

I hope this helps! Let me know if you have any other questions. Happy calculating!
