Convert the expression in sympy compilable expression.

Parameters¶

exprstr or sympy.Expr: The string representation of the equation. Some operators like multiplication can be implicit.

Examples¶

>>> from cutcutcodec.core.compilation.parse import parse_to_sympy
>>> parse_to_sympy(0)
0
>>> parse_to_sympy("1/2 + 1/2*cos(2pi(t - i*j))")
1*cos(2*pi*(-i*j + t))/2 + 1/2
