Use MATLAB live scripts instead.MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.Syntaxerf(x) Descriptionerf(x) represents the error function 2π∫0xe−t2dt.This function is defined for all complex arguments x. For floating-point arguments, erf returns floating-point results. The implemented exact values are: erf(0) = 0, erf(∞) = 1, erf(-∞) = -1, erf(i ∞) = i ∞, and erf(-i ∞) = -i ∞. For all other arguments, the error function returns symbolic function calls.For the function call erf(x) = 1 - erfc(x) with floating-point arguments of large absolute value, internal numerical underflow or overflow can happen. If a call to erfc causes underflow or overflow, this function returns:The result truncated to 0.0 if x is a large positive real numberThe result rounded to 2.0 if x is a large negative real numberRD_NAN if x is a large complex number and M

Copy the above code to a file 'stat.m' and it should work. This policy does cause an unnecessary number of short files, but it is required because of the way matlab handles variable scope. Each file gets its own scope, and all variables in the command prompt have global scope. share|improve this answer answered May 11 '11 at 19:36 Quantum7 88321223 i cope this code to another file , and run it , but repeat this error –roghie May 11 '11 at 19:52 @roghie: Make sure not to copy the line syms T1 T2 to the file. Only function and everything after. –gnovice May 11 '11 at 19:57 i do this. but the error is repeat –roghie May 11 '11 at 20:03 add a comment| up vote 2 down vote As Quantum7 pointed out, you have defined the function
