binary matrix multiplication

[sumalama]

Hi,

How do I multiply two binary matrices in labview? tried using boolean OR operator but it is not working

thanks

Hi sumalama,

please attach a VI containing your two factors of that multiplication and the expected result!

LabVIEW doesn't know of an error message like "it's not working"...

Hi sumalama,

What do u mean by multiplication in this instance??

Please check this is what u need?

Hi,

I have attached the screenshot of my VI, please have a look

thanks

Hi sumalama,

is there a reason to use matrix datatype instead of plain 2D arrays?

When you want to use boolean operations you're bound to use arrays. Convert the matrices into arrays (if possible boolean arrays) and use the functions of the boolean palette!

Even with matrices it does function!

Though 2D arrays are recommended, so you can use boolean arrays

Hi Koen,

I would be very careful to wire DBL values to a boolean function. Please try your snippet with different values than just 0 and 1...

[KoenR94]

Yes you are right, but he was talking about booleans.

But you are right DBL's aren't that great for comparison

Hi,

I had used the arrary first and it gives me unexpected result, dimension is not correct, attached is screenshot. I want to multiply the two matrices so i am using OR function.

thanks

Hi sumalama,

now we getting to the core of the problem: You're mixing array operations with mathematical matrix calculations!

That's what I meant with "attach a VI with values and expected result"...

Please look in the mathematics->linear algebra functions palette and pick the correct functions to "multiply" two arrays. The correct wording should be "A×B" (cross/vector product)!

Btw. the boolean OR is usually the replacement for an addition, while the AND is considered the "boolean multiplication"...
