MM_TO_ST
Matrix Market File
converted to
ST Sparse Triplet File

MM_TO_ST is a MATLAB program which accepts the name of a file containing a sparse matrix in the Matrix Market File Format, and which reads that data and writes a corresponding ST Sparse Triplet file.

Source Code:

• mm_to_msm.m reads a Matrix Market file and returns a MATLAB Sparse Matrix.
• mm_to_st.m reads a Matrix Market file and writes an ST Sparse Triplet file.
• msm_to_st.m accepts a MATLAB Sparse Matrix and writes an ST Sparse Triplet file.
• st_data_write.m, writes the data of an ST file.
• st_header_write.m, writes the header of an ST file.
• st_rebase.m, changes the base of an index array.
• timestamp.m, prints the current YMDHMS date as a timestamp.

Examples and Tests:

• mm_to_st_test.m, uses MM_TO_ST to convert a file.
• mm_to_st_test_output.txt, the output file.
• wathen_29_29_adg.mm, the MM file to be read.
• wathen_29_29_adg.st, the ST file to be created.
