2fwrite
Purpose Write binary data to a file
Syntax count = fwrite(fid,A,precision)
count = fwrite(fid,A,precision,skip)
fwrite
Description count = fwrite(fid,A,precision) writes the elements of matrix A to the
specified file, translating MATLAB values to the specified precision. The data
is written to the file in column order, and a count is kept of the number of
elements written successfully.
Examples For example,
fid is an integer file identifier obtained from fopen, or 1 for standard output or
2 for standard error.
precision controls the form and size of the result. See fread for a list of
allowed precisions. For 'bitN' or 'ubitN' precisions, fwrite sets all bits in A
when the value is out of range.
count = fwrite(fid,A,precision,skip) includes an optional skip
argument that specifies the number of bytes to skip before each precision
value is written. With the skip argument present, fwrite skips and writes one
value, skips and writes another value, etc., until all of A is written. 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.
fid = fopen('magic5.bin','wb');
fwrite(fid,magic(5),'integer*4')
creates a 100-byte binary file containing the 25 elements of the 5-by-5 magic
square, stored as 4-byte integers.
