Error in using an element in a matrix as function input

I have an array/vector c, and I want to use it as input for my function, Viscosity like this:

function fv=Viscosity(c(1), c(2), c(3), c(4), c(5), c(21),c(24))

However, I am receiving this error:

Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

You need to pass the entire array, or treat each element as a separate variable. You can of course create the c array inside your own function.

Functions in Matlab are intended to not care about anything in the calling workspace, just the input arguments and output arguments.
