Error using CheckNetworkData (line 39)
H_PARAMS must be numeric.
Error in h2s (line 17)

Hi grace,
The 'h2s' function expects the 'H_PARAMS' to be of numeric Type. The error that you have mentioned in the question arises when the 'H_PARAMS' passed as arguments are not of numeric type.
You can use the 'isnumeric' in Matlab function to see if the provided 'H_PARAMS' are of numeric type, and make changes accordingly.
Hope this helps!
