Hello, we are trying to find the normal distribution of an array using the code below. However we are receiving the error that X must be a numeric column vector. Is there any way to apply the function to all columns? Thanks!

Yes, use varfun(), assuming the table contains all numeric values.
mu = varfun(@mean, FilledTrtnPos)
or
fitTable = varfun(@(c)fitdist(c,'Normal'), array2table(rand(10,4)))

Why doesn't my answer address that?
A normal distribution has 2 parameters: center (mean) and width (standard deviation). varfun could be used to compute both for each column of a table.

You are correct, my apologies I misunderstood a normal distribution earlier.
