This library contains routines for file I/O (in io.c) as well as the Numerical Recipes utilities (for memory allocation). The latter is slightly modified to include new matrix types (like cmatrix). The file formats supported in io.c include: raw binary files DAT-format files raw PGM-format files (with *no* comments!) BF-format files BF is my own format for storing binary float images which consists of two floats (4 bytes each) denoting the number of rows and columns (in that order) followed by the rest of the data (1 4-byte float per pixel in raster sequence): ....
