## Particular cases

Empty matrix and substraction

  In Matlab, substraction can only be made if the operands have the same size unless one is a scalar. For exemple, empty matrices can only be substracted to another empty matrix or a scalar. Note that when you substract an empty matrix to a scalar and inversely, Matlab result is always an empty matrix while in Scilab, result is equal to the scalar.

## Examples

    A = 1 - []
    A = []

    A = 1 - []
    A = 1
