Hi,
the following raises in error in the 3.0 branch:
polyfit ([1,2; 3,4], [1,2; 3,4],4)
namely
error: polyfit: x and y must be vectors of the same size
In fact, this error is part of test_poly.m in the test/ subdirectory.
In the development sources, the test has been removed and the output is
now:
octave:1> polyfit ([1,2; 3,4], [1,2; 3,4],4)
ans =
0.011358 -0.113585 0.397547 0.432076 0.272603
Is this change intentional, ie should polyfit handle matrices as input
arguments?
Thomas
