Singular radius
Alias: none
Argument(s): REAL
Default: -1. (use NL2SOL internal default of 1)
singular_radius
works in conjunction with singular_conv_tol to test for underdetermined least-squares problems (stop when the relative reduction yet possible in the sum of squares appears less than singular_conv_tol
for steps of scaled length at most singular_radius).
The internal default results in the internal use of steps of length 1. The default is selected with a value of -1.
