isreal (Matlab function)

Determine if all array elements are real numbers

Matlab/Scilab equivalent

Matlab Scilab

Particular cases

Scilab isreal function can take two values as input. The first one is the same as Matlab one and the second allows to give a tolerance on the absolute value of the imaginary part of first input. So to have the same results in Matlab and in Scilab, second input in Scilab function must be set to 0.

Examples

Matlab Scilab
tf = isreal(1+0i)
tf = 1
tf = isreal(1+0*%i)
tf = %F
tf = isreal(1+0*%i,0)
tf = %T
