Updated to have all element wise tensor operations be an instance of the lin::internal::StreamElementWiseOperation<class F, class... Cs>class and be based off of functors.
Added more element wise operations (see include/lin/core/operations/operations.hpp) and operators (see include/lin/core/operations/operators.hpp).
Without writing a ton, there are a whole new set of element wise operation functions that include: lin::add, lin::divide, lin::multiply, lin::negate, lin::sign, lin::multiply, etc which will always perform an element wise operation.
For example, the following code is equivalent to using .* in MATLAB:
lin::Matrix2x2f A { ... }, B { ... };
lin::Matrix2x2f C = lin::multiply(A, B);
These functions can also take a scalar in as any argument to, as an example, add 5.0 to every element of a matrix/vector:
lin::Matrix2x2d A = { ... };
A = lin::add(5.0, A);
Most of the above operations can be expressed using operator overloads as well; for example, lin::add(5.0, A) is equivalent to 5.0 + A. There is, however, the notable exception regarding lin::multiply. A * B from the example above would perform matrix multiplication; lin::multiply must be used explicitly for element wise multiplication.
