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.
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
