Hi everyone, new on here so if what i am asking has already been covered please direct me to the right place.

Right, I just got a new FX-570 and I am struggling with the Matrix side of the calculator. As with most Casio products the instruction manual is a nightmare so I have come here for some help.

What I want to do is multiply two matrices, not too difficult eh!

Well, I enter the values from Matrix A, then enter the values for matrix B, try and multiply them together and get a dimension error. Then I look for the values in matrix B and they are still there, but when I look for the values in Matrix A they are not there.

I am guessing that you may need to load the values for each matrix into memory but I a not sure on that. Any advice would be great.

Thanks.

Should work, give it a try (at least worked with my 991ES)
