Function and vector inputs

Please provide a worksheet with (an example of) what you are trying to do.

State the version of Prime you are using.

Success!

I agree with Luc that an example sheet which shows what you actually are trying to achieve would be necessary for further help.

Here just a shot in the blue

Lets assume you want to solve the equation (you can't solve a "function"!)

for c, input values are a and b and you want to solve it for a couple of a- and b- values which you provide as vectors.

One way could be to symbolically solve the equation and turn the result into a function sol1( ) of a and b.
Then you call that function with the vectors as arguments (you should use vectorization when you do so).

Another way is to use the numeric root function in a similar way
