all (Matlab function)

Test to determine if all elements are nonzero

Matlab/Scilab equivalent

Matlab Scilab

Particular cases

Matlab all function can work with complexes, what Scilab and can not, so a call to abs function can be necessary when translating from Matlab to Scilab.

The Matlab expression B=all(A) is translated into Scilab by B=and(A):

If A is a matrix, all(A) is equivalent to all(A,1) in Matlab whereas in Scilab and(A) is a logical AND of all elements of A. If A is a multidimensional array then Matlab treats the values along the first non-singleton dimension, but Scilab returns logical AND of all elements of A.

The Matlab expression B=all(A,dim) is translated into Scilab by B=and(A,dim):

In Scilab dim=1 is equivalent to dim="r" and dim=2 is equivalent to dim="c". In Matlab, dim can be greater then the number of dimension of A (in this case, B=A), in Scilab you will get an error message.

y = %F
y = and([1,1,0;1,0,1],1)
y = [%T,%F,%F]
