Random "Function definitions are not permitted in this context." When running integral

Hi,

My Matlab refuses to run the "Intgeral" function. When I run this piece of code, I get a weird error:

>> integral(@(z) z.^2, 0,1)
Error: File: integralCalc.m Line: 1 Column: 2
Function definitions are not permitted in this context.

Error in integral (line 88)
Q = integralCalc(fun,a,b,opstruct);

It doesn't happen if I use integral2 in the same context:

>> integral2(@(z,t) z.^2, 0,1,0,1)

ans =

      0.3333

Clear workspace doesn't change anything, so as restarting Matlab.

This didn't happen before, and I just started happening one day.

Thanks, Yotam

It does not happen to me. Did you perhaps overwrite the integralCalc.m file? It should start with the word function.

Hi Jos,

Where should I look for this file? thanks, Yotam

Please show the output of
