Name

all — (Matlab function) Test to determine if all elements are nonzero

Matlab/Scilab equivalent

Matlab Scilab
all
and

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.

B=all(A) <--> 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.

B=all(A,dim) <--> B=and(A,dim)

In Scilab dim=1 is equivalent to dim=''r'' and dim=2 is equivalent 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.

Examples

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