I'm calculating some gradients with symbolic variables and after that I want to insert values for the variables.
So I have a function depandent of multiple variables x(1),..., x(20)
and I want to insert some values for the variables, something like
such that the function replaces all the x(1) values with 10 and x(20) values with 14
How is that done? Should be simple but I can't find anything helpful explaining how to solve this
