CSQRT function

Description

CSQRT(x) takes a complex or real number as argument and returns its square root. When x is a negative real number the result is a complex number. CSQRT(-1) returns 0+1i.

The argument x can be a real number, a complex number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the CSQRT function applied to all elements.

Example

CSQRT(-1) returns 0+1i

CSQRT(9) returns 9.
