SUMMARY

The discussion focuses on calculating the mean of columns in a matrix containing NaN values using MATLAB. The matrix A is defined as A = [1 2; nan 3; 3 4]. The solution provided utilizes the MATLAB function 'mean' with the 'omitnan' option, resulting in the output avg = [2, 3]. This method effectively ignores NaN values in the calculation, ensuring accurate column averages.

Hi PF!

Given a matrix A = [1 2; nan 3; 3 4], how can I calculate the mean so that the resulting matrix averages the columns but ignores the nan values as non-entries, so that the mean of matrix A outputs [2,3]?

Thanks so much!
