When defining a1, b1, c1.. etc, you define them as rows of a matrix (notice how they are still in parenthesis), and they remain a single entry matrix. This causes an error later on since you can't take a derivative of a matrix.
Instead of extracting the row, extract the element by using the "el" function, or write the matrix name followed by "[" and the row number.
eg. a.1 : M[1

The cases() function helps a lot in writing piecewise continuous functions in a readable way.
