Let's say we have 2 equations and 3 variables (N equations and M variables, where M > N), for example:
0.3a+0.1b+0.2*c=10 + E
0.1a+0.2b+0.3*c=11 + E
We want to find a, b, c that are in the range [0.0, 1.0] and we want to minimize the error E.
We want a smooth solutions that in this context means that if we chart a, b, c in a chart, the chart is smooth.
How this kind of problems can be approached with sagemath?
