matrix operation to scalar

Hi,

I have an operation c(t,1)/a(t,1) which takes as inputs an element from both a c and a vector. The output of this operation is a number. I would like to save this number as a scalar for the rest of the code. How can I do this? When I type in:

c = c(t,1)/a(t,1)

I get the following:

"Index in position 1 exceeds array bounds. Index must not exceed 1."

Thanks a lot!

Don't overwrite your vector variable with a scalar value then attempt to use it as though it were still a vector.

If you have a stick of butter (usually 8 tablespoons) and you use 7 tablespoons of it, you can't then use 2 tablespoons from that same stick. You don't have enough.

stickOfbutter = ones(1, 8)

stickOfbutter = 1×8

1 1 1 1 1 1 1 1

butterForRecipe1 = stickOfbutter(1:7);
stickOfbutter(1:7) = [] % I used 7 tablespoons for recipe 1

stickOfbutter = 1

butterForRecipe2 = stickOfbutter(1:2) % Error, not enough

Index exceeds the number of array elements. Index must not exceed 1.
