Bug report for Octave 1.94 configured for i586-pc-linux-gnu
Description:
-----------
A matrix assignment of the form
A(:,1) = some_colum_vector
does not work, when A has not been defined before. This kind of
assignment was possible in previous versions.
Repeat-By:
---------
octave:1> a(:,1)=rand(3,1)
error: A(I, J) = X: X must be a scalar or the number of elements in I must
error: match the number of rows in X and the number of elements in J must
error: match the number of columns in X
error: evaluating assignment expression near line 1, column 7
