Single bit read returning invalid precision
Show older comments
code to read a .wdq file is returning an invalid precision error when reading one bit.
info.hiResFile = fread(fid, 1, '*ubit1');
is the line refrenced in this error:
error: fread: invalid PRECISION specified
but as far as I can tell '*ubit1' is a valid precision value to read a single bit of data.

The first parameter to fread() must be a file identifier, not a file name.
filename = 'a.wdq';
[fid, msg] = fopen(filename, 'r');
if fid < 0
error('failed to open file "%s" because "%s"', filename, msg);
end
b = fread(fid, 1, 'ubit1')
