I want to calculate AUC score by using trapz function , integrating across rows. My matrix has dimension (180*10). So, There should be a table with 180 rows a and one column of AUC scores.

output should contain 180 rows and one column.

Are you talking about Area Under Curve-AUC? If you apply in the complete matrix having the stated dimension, I don't seem any problem.

To repeat:

From the documentation:

• Q = trapz(_,dim) integrates along the dimension dim using any of the previous syntaxes.

So to integrate across rows, use 2 for ‘dim’.

A more specific example with ‘A’ as your array:

AUC = trapz(A,2);
