SQRT Square Root of an Array

Section: Mathematical Functions

Usage

Computes the square root of the argument matrix. The general syntax for its use is
   y = sqrt(x)

where x is an N-dimensional numerical array.

Example

Here are some examples of using sqrt
--> sqrt(9)
ans = 
  <double>  - size: [1 1]
 3  
--> sqrt(i)
ans = 
  <complex>  - size: [1 1]
 0.70710677+0.70710677 i  
--> sqrt(-1)
ans = 
  <dcomplex>  - size: [1 1]
 6.123031769111886e-17+1.000000000000000e+00i  
--> x = rand(4)
x = 
  <double>  - size: [4 4]
