MATLAB Code: Calculating Relative Deviation from Mean

This code calculates the relative deviation of the variable 'fwork_tem' from its mean value.

1. 'mean(fwork_tem, 'all')' calculates the mean value of 'fwork_tem' for all elements in the array, regardless of their position.

2. 'mean(fwork_tem, 'all')' is subtracted from 'fwork_tem' to obtain the deviation of each element from the mean.

3. The deviation is then divided by the mean value to obtain the relative deviation or the ratio of deviation to the mean value.

4. The resulting array is assigned to the variable 'fwork_index'.
