Dear members

I have a matrix H of type uint8 and a vector V of type double

When I make

D=mod(H*V,2);

I get an error : MTIMES (*) is not fully supported for integer classes. At least one argument must be scalar

I tried to convert the matrix from uint8 to double by making :

H=double(H);

but it doesn't work. How can I fixe the problem please

What does "but it doesn't work" mean exactly? Does it throw an error message? (if so, what is the complete error message?) Or do you get an unexpected value? (if so, please upload sample data by clicking the paperclip button).

Try convert H to double first.

D=mod(double(H)*V,2);

@Chunru

class(H)
ans =
    'uint8'
    
classe(V)
ans =
    'double'

Then the following command should be correct:

D=mod(double(H)*V,2);

You may want to post the portion of code that give the error, together with the code generate H and V.
