MATLAB: Mean/average of a variable

arrayaveragecalculatemean

Hello,

I have a variable P(a,b,c) where a=2, b=1:150,c=1:100.

Now, for each value of c, I want to calculate the mean of P:

M=mean(P(a,1:150,:))

where at the end I should have an array M(1,100).

Using what I showed above it does not work.

Coudl anyone help me?

Thanks in advance!

M=mean(P(a,1:150,:),2)

Hi,

I think you forgot to specify the dimension. Try

C = mean([ A(B(:,1)), A(B(:,2))],2)

To achieve this you can use function min and function mean

Lets say

A = [1.7 1.2 1.5; 1.3 1.6 1.99]
% use min function to get smallest element from each row.
M = min(A,[],2)
% use mean function
result = mean(M)
