![]() ![]() ![]() Two formats map to an input steam of bits rather than bytes:Ĭreates a 100-byte binary file, containing the 25 elements of the 5-by-5 magic square, stored as 4-byte integers. If you always work on the same platform and don't care about portability, these platform-dependent numeric precision string formats are also available: MATLAB ![]() If you are a C or Fortran programmer, you may find it more convenient to use the names of the data types in the language with which you are most familiar. For convenience, MATLAB accepts some C and Fortran data type equivalents for the MATLAB precisions listed. The tables below give C-compliant, platform-independent numeric precision string formats that you should use whenever you want your code to be portable. Remarks Numeric precisions can differ depending on how numbers are represented in your computer's architecture, as well as by the type of compiler used to produce executable code for your computer. If precision is a bit format like 'bitN' or 'ubitN', skip is specified in bits. This is useful for inserting data into noncontiguous fields in fixed-length records. With the skip argument present, fwrite skips and writes one value, skips and writes another value, etc. Includes an optional skip argument that specifies the number of bytes to skip before each precision value is written. Argument fid is an integer file identifier obtained from fopen. (See "Remarks" for more information.) The data are written to the file in column order, and a count is kept of the number of elements written successfully. If Xis of class double, the imwritefunction offsets the values in the array before writing, using uint8(X-1). If Xis of class uint8or uint16, imwritewrites the actual values in the array to the file. Writes the elements of matrix A to the specified file, translating MATLAB values to the specified numeric precision. imwrite(X,map,filename,fmt)writes the indexed image in Xand its associated colormap mapto filenamein the format specified by fmt.
