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 = 
 3 

--> sqrt(i)

ans = 
   0.7071 +  0.7071i 

--> sqrt(-1)

ans = 
   0.0000 +  1.0000i 

--> x = rand(4)

x = 
    0.4871    0.5309    0.3343    0.1123 
    0.7049    0.6431    0.3320    0.7799 
    0.5845    0.8331    0.9892    0.9155 
    0.5407    0.9178    0.3408    0.2274 

--> sqrt(x)

ans = 
    0.6980    0.7286    0.5782    0.3352 
    0.8396    0.8020    0.5762    0.8831 
    0.7645    0.9127    0.9946    0.9568 
    0.7354    0.9580    0.5838    0.4769
