Multiple two different vectors

[YA_10963798]

Hi everyone,

I want to use two different vectors in one equation ...what should be the iterator f ,q and dz 

I used length function but it gives me strange results

Vectorization can only be used if all involved vectors/matrices are of the same dimension.

Its absolutely not clear to me what you expect as the result of this calculation. Maybe one single 3x1 vector??

A simple short example worksheet with a few corresponding demo vectors and the indication of the desired result would be very beneficial.

The problem is I'm  lost. myself . I don't know what's my question is ... hhhhhh I will try to solve it . Sorry for wasting your time 

Thanks anyway my friend

You wrote that your second attempt gave you "strange results". So that means that you expected a different result - which one?

Do you see the f and q both of them have 3 matric ... The matrics in first raw (10X1) is actually the corresponding values of dz .. what I want to do is to multipy dz with the frist raw and then do the same in the second raw ... and the result of M should look like q >>> three matrices 

I will write demo worksheet and upload it right away

So why not set up a small worksheet with a few vectors/variables of similar dimensions and post it, so we can show whats needed to do?

Its hard to explain just in words...

Try this

Sure .. See I have x and y both of them has 3 matrices I want to multiply z with first matrics of both of them like ( x*y*z)=(1*7*5) and then (2*5*8) in the first matrics raw  and  then does the same in the second matric so on... and j should look like x and y ..... the sheet is attached

Hope this is what you are looking for

Perfect .... Thank you

Here is another way using an auxiliary function instead of the range k.

But its harder to read and to understand whats going on so I would prefer the variant using the range

And of course you could explicitly program the loops which are performed implicitly by the range and the vectorization

Nice .. thank you
