Solving TL Problem..

There are a few points that will need to be clarified before we can find a solution to your question.

In the snip above you define a function TL_degeri with a parameter f, but the first statement of the program is re-defining that as a range 0 to 100; the value for f at all points following this will be 100.

the for loop that you define only includes the k[1 statement everything after that will only calculate once
all statements that are inlcuded in he for loop should be indented as the K[1.

If you wish to add more lines here then you need to select the line as here before inserting new line(s):

are these what you intended or is this the first part of the solution

Apart from what Andy has pointed out, you ar using matrix indices 1 and 2 where you should have used 0 an 1 (or as an alternative could have set ORIGIN to 1).

Furthermore HxL(f) seems not to be invertible in all case which throws an error, too.
