MATLAB: Symbolic Math Toolbox: Just installed: tried first example: ‘sym(1/3)’: system hangs: Help

symbolicSymbolic Math Toolbox

I just received my download and installed Symbolic Math Toolbox. I just started executing Getting Started example… 'sym(1/3)'. Once I hit 'enter' MATLAB hangs. Reinstalled… Still same issue.

Help.

MATLAB: Symbolic Toolbox: integration

Apparently you have to do the substitution manually

int(simple(cos(x^2)^2))
Warning: Explicit integral could not be found.

Using the sincos version returned by

simple(cos(x^2)^2)

yields this

int(cos(2*x^2)/2 + 1/2)
ans =
x/2 + (pi^(1/2)*fresnelC((2*x)/pi^(1/2)))/4

I could not find where the sincos 'simplification' is available outside the simple command as it is in Maple...maybe this is the reason Maple returns the result automagically ;)

[edit for completeness]

int(feval(symengine, 'combine', cos(x^2)^2, 'sincos'))
ans =
x/2 + (pi^(1/2)*fresnelC((2*x)/pi^(1/2)))/4
