For Howard Schoeberlein, I recently learned from Matlab that the reason for the error that you received is due to the fact that the dll was compiled with Compaq fortran, not now supported in current (2008b) matlab vesion. I just found it myself. I'd provide you the source file if you write.

This doesn't work in MATLAB V2007a and 2007b. The problem seems to be in the dll file. I get the following error message:

??? Invalid MEX-file 'C:\My MATLAB Work\Johnson
Curves\cmu_as99_johnson_pdf.dll': The specified procedure could not be found.

.

Error in ==> johnson_fit at 42
[gamma,delta,lambda,xi,itype,ifault] = cmu_as99_johnson_pdf(xbar,sd,rb1,bb2);

Note that it seems to be complaining about a proceudre called ".", strange as that is.
