Ran that now with a trivial example to see if it works at all in octave

a = rand(20,10);
b=rand(20,1);
x = lsqrSOL(20, 10, a, b, 0, 1e-9, 1e-9, 1e8, 1000, 1);
max(abs(x-a\b))
ans =  1.8536e-15

I will investigate this evening how the call syntax can be simplified,
at least the dimensions are not needed as long as a is a matrix and for
the other parameters except a and b defaults would be fine and a few
tests on performance and resource use.

The test script fails since it uses nested functions, needs to be changed.
