realsqrt

Squareroot for nonnegative real arrays

Syntax

Y = realsqrt(X)

Description

example

Y = realsqrt(X)returns the square root of each element of arrayX. The size ofYis the same as the size ofX.

If you want negative and complex numbers to return complex results instead of error messages, then usesqrtinstead.

Examples

collapse all

Create a 4-by-4 matrix of real, positive values.

X = magic(4)
X =16 2 3 13 5 11 10 8 9 7 6 12 4 14 15 1

Compute the square root of each element inX.

Y = realsqrt(X)
Y =4.0000 1.4142 1.7321 3.6056 2.2361 3.3166 3.1623 2.8284 3.0000 2.6458 2.4495 3.4641 2.0000 3.7417 3.8730 1.0000
