Base 2 power and scale floating-point numbers
X = pow2(Y)
X = pow2(F,E)
X = pow2(Y) returns an
X whose elements are 2 raised to the power
X = pow2(F,E) computes x = f *
2e for corresponding
E. The result
is computed quickly by simply adding
E to the floating-point
real and integer arrays, respectively.
For IEEE® arithmetic, the statement

This function corresponds to the ANSI® C function
the IEEE floating-point standard function
This function fully supports tall arrays. For more information, see Tall Arrays.
