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.

Use PetscBinaryWrite('filename',sparsematlabmatrix) I do not know why your second argument has quotes around it.

Hello,
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;
PetscBinaryWrite('matrix.mat','output.ex') 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.
Thanks in advance,
Tom
