realsqrt

Squareroot for nonnegative real arrays

Syntax

``Y = realsqrt(X)``

Description

example

````Y = realsqrt(X)` returns the square root of each element of array `X`. The size of `Y` is the same as the size of `X`.If you want negative and complex numbers to return complex results instead of error messages, then use `sqrt` instead.```

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 in `X`.

`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 ```

Input Arguments

Input matrix, specified as a scalar, vector, matrix, or multidimensional array. The values in `X` must be nonnegative and real.
