How to compare class type of 2 variables to find equality and use it within switch-case

I am trying to make a statement using switch case block and I want to know how thats possible with 2 variables?

I am supposed to add variables a and b if the case is 'double' but how would I do that if:

a = [1 2 3 4]

b = [2 1 3 1] ? So far I was thinking of doing this.

a = [1 2 3 4]

b = [2 1 3 1]

c = class (a)

d = class (b)

e = c == d

       switch blah

       case 'double'

       a + b

       case 'logical'

       a & b

       otherwise

       disp ('None')

       end

and so on

Now I need a switch and case block to create a scenario where if our switch x has the case 'double' (class type) it will add variables a and b.

Any help will be much appreciated. Thank You

What if you simply switched on the value of c? E.g.,

switch c

Does this do what you want? Or is there something else you need? Maybe add a check to see if a and b are the same class, e.g. check that isequal(c,d) is true.

No because i want to check for the class of a and b. and i cant just do switch c because that doesnt take e into account i need both class of a and b to be double in order for the statement to add a and b together

[James Tursa]

That's why I suggested adding a check for that using isequal(c,d). E.g., something like this

if( isequal(c,d) )
    switch c
        case 'double'
            a + b
        case 'logical'
            a & b
        otherwise
            disp('None')
    end
else
    error('Classes must match');
end

But i cant use the if statement. :/

You could stack the classes side by side. E.g.,

    switch [c,d]
        case 'doubledouble'
            a + b
        case 'logicallogical'
            a & b
        otherwise
            disp('None')
    end

Thank You so much!!! thats all i needed to know. Stack side by side.
