What files should one use to convert vectors from Matlab to PETSc (PetscBinaryWrite is for square matrices)?  I have attempted to write directly to binary from Matlab a matrix + vector, and only a vector (using save command with the -mat option), then read the binary file into PETSc (using ex34.c in ...src/mat/tests), however the format is not recognized.<br>

   Use PetscBinaryWrite(&#39;filename&#39;,sparsematlabmatrix)  I do not know why your second argument has quotes around it.<br>

&gt; Hello,<br>
&gt;<br>
&gt; I am new to PETSc and programming.  I have a question concerning writing PETSc matrices in binary from binary matrices [compressessed/uncompressed] generated in Matlab.  I am attempting to use the files in the /bin/matlab directory, in particular the PetscBinaryWrite.m file.  However, the usage;<br>

&gt;<br>
&gt; PetscBinaryWrite(&#39;matrix.mat&#39;,&#39;output.ex&#39;) does not seem to work.  I also tried using the examples in the /mat directory however, matlab does not support the writing of complex matrices in ASCII.<br>

&gt; Thanks in advance,<br>
