Divide by Zero when using curve = fitting.approximate_curve(tuple_list, 3)

[KeithSloan]

Have code that is executing

curve = fitting.approximate_curve(tuple_list, 3)

File "/Users/keithsloan/Library/Application Support/FreeCAD/Mod/toSketch/./freecad/toSketch/toSharedFunc.py", line 387, in fit_bspline_to_geom_geomdl
curve = fitting.approximate_curve(tuple_list, 3)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

x = linalg.backward_substitution(matrix_u, y)

matrix_x[i] /= float(matrix_u[i][i])
