Usage
Writes an array to a given file handle as a block of binary
(raw) data. The general use of the function is
n = fwrite(handle,A)
The handle argument must be a valid value returned by the
fopen function, and accessable for writing. The array A is
written to the file a column at a time. The form of the
output data depends on (and is inferred from) the precision
of the array A. If the write fails (because we ran out of
disk space, etc.) then an error is returned. The output n
indicates the number of elements successfully written.
Note that unlike MATLAB, FreeMat 4 does not default to uint8
for writing arrays to files. Alternately, the type of the
data to be written to the file can be specified with the
syntax
n = fwrite(handle,A,type)
where type is one of the following legal values:
* 'uint8','uchar','unsigned char' for an unsigned, 8-bit
integer.
* 'int8','char','integer*1' for a signed, 8-bit integer.
* 'uint16','unsigned short' for an unsigned, 16-bit integer.
* 'int16','short','integer*2' for a signed, 16-bit integer.
* 'uint32','unsigned int' for an unsigned, 32-bit integer.
* 'int32','int','integer*4' for a signed, 32-bit integer.
* 'single','float32','float','real*4' for a 32-bit floating
point.
* 'double','float64','real*8' for a 64-bit floating point.
Example
Heres an example of writing an array of 512 x 512 Gaussian-
distributed float random variables, and then writing them to
a file called test.dat.
--> A = float(randn(512));
--> fp = fopen('test.dat','w');
--> fwrite(fp,A,'single');
--> fclose(fp);
