Plus

Matlab/Scilab equivalent

Matlab Scilab
+
+

Particular cases

Character strings addition:

In Scilab, string addition is the same as string concatenation, what is done in Matlab by strcat function. In Matlab, string addition is the equivalent of the addition of corresponding ASCII codes.

Empty matrix and addition:

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

Unary plus:

In Matlab, unary plus exists, but in Scilab it is automatically deleted when compiling so we can consider that Scilab unary plus does not exist.

Examples

Matlab Scilab
str = 'str1'+'str2'
str = [230,232,228,99]
str = strcat('str1','str2')
str = 'str1str2'
A = 1 + []
A = []
str = 'str1'+'str2'
str = 'str1str2'
str = strcat(['str1','str2'])
str = 'str1str2'
A = 1 + []
A = 1
