help sqrt

SQRT Square root.
SQRT(X) is the square root of the elements of X. Complex
results are produced if X is not positive.

See also SQRTM.

help abs

ABS Absolute value.
ABS(X) is the absolute value of the elements of X. When X is complex, ABS(X) is the complex modulus (magnitude) of the elements of X.
