The norminv function is not working in my code. i have included the error message I am receiving. I obtained this function from the Oxford MFE toolbox website. Any suggestions?

Undefined function 'iscompatible' for input arguments of type 'double'.

Error in norminv (line 34) [err, errtext, sizeOut, mu, sigma] = iscompatible(2,mu,sigma,size(p));

Error in E92qcov (line 64) zq=norminv(0.01,0,1);

Oops. Forget my other answer.

The Oxford MFE Toolbox is assuming you have the Financial Toolbox installed, which has the iscompatible function.

Thanks very much for this.

Hm. Maybe I have a later version, but my norminv does not call a function called iscompatible. I am guessing that this may not be the MATLAB version, and we may not be able to help you much.

What do you get if you type

which -all norminv

?
