MATLAB: Finding the mean of a matrix row? Get error “Subscript indices must either be real positive integers or logicals.”

Question

If I have the following matrix as an output from my code;

Xtcounter =

     0     4     4     4     0
     0     4     4     4     0
     0     4     4     4     0
     0     4     4     4     0
     3     4     4     1     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0
     2     4     4     2     0

where each row represents particle's positions along the axis at a time.

I want to find the mean value of each row but it wont let me, I have tried various methods such as

A=Xtcounter(2,:) M=mean(A)

but get the error message;

Subscript indices must either be real positive integers or logicals.

If anyone could help it would be so appreciated!! As i will need to be able to do standard deviation, kurtosis and skewness of each row after!

Thanks in advance!!

Answer 1

Use

 A = mean(Xtcounter,2)
 B = std(Xtcounter,0,2)
 C = kurtosis(Xtcounter')'
