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 = <double> - size: [1 1] 3.000000000000000 --> sqrt(i) ans = <complex> - size: [1 1] 0.70710677 0.70710677 i --> sqrt(-1) ans = <dcomplex> - size: [1 1] 6.12303176911189e-17 1.000000000000000 i --> x = rand(4) x = <double> - size: [4 4] Columns 1 to 2 0.814723686393179 0.632359246225410 0.905791937075619 0.0975404049994095 0.126986816293506 0.278498218867048 0.913375856139019 0.546881519204984 Columns 3 to 4 0.957506835434298 0.957166948242946 0.964888535199277 0.485375648722841 0.157613081677548 0.800280468888800 0.970592781760616 0.141886338627215 --> sqrt(x) ans = <double> - size: [4 4] Columns 1 to 2 0.902620455337225 0.795210189965779 0.951731021389772 0.312314592997845 0.356352095957784 0.527729304536946 0.955706992827310 0.739514380661380 Columns 3 to 4 0.978522782276579 0.978349093239701 0.982287399491247 0.696689061721828 0.397005140618542 0.894583964135732 0.985186673560202 0.376678030454678
