I cannot call most of the matrix operations

[Hakan Yüksel]

Hello,

I have configured and compiled octave.2.1.73 with following options:

       ./configure --prefix=/usr \
                   --with-blas \
                   --enable-shared \
                   --with-hdf5 \
                   --enable-rpath \
                   --with-lapack \
                   --disable-nls \
                   --enable-readline \
                   --enable-picky-flags \
                   --with-g77 \
                   --with-x

       make
       make install

Gcc version is 4.1.1.

When I want to call det(A), inv(A) or pinv(A) I get the following line:
"error: `inv' undefined near line 8 column 1".

But "A^-1" works. What's wrong with my installation?

With kind regards, Hakan
