I have a child function being called inside the original code. Can I have the function be able to access all of the variables (workspace) from the original code? If so, how?

A nested function can access the variables stored in the workspace of its caller function:
function x = outer_function(a,b)
x = inner_function;
function y = inner_function
y = a + b;
end
end
>> outer_function(2,3)
ans =

Note: this strategy cannot be used to access a variable which exists in the caller function if the same variable name appears in an input or output position in the "function" declaration of the inner function.

evalin('caller', 'who') to find the list of variables, and further evalin('caller') to get each of the values.
