Write to binary - undefined function or method fwrite for input arguments of type uint8

Hi,

I have data in an matrix called LU I'm trying to write to a binary file. LU is of type uint8 and I need big endian encoding. I use: fid=fopen('00001-00600.00001-00600','w')

fwite(fid,LU,'uint8',0,'b')

But then I get the following error: undefined function or method 'fwrite' for input arguments of type 'uint8'

Why does this happen and how can I solve it?

That error should only be generated if the very first argument to fwrite() is of close uint8. Please re-check your code as you likely have a place in which you forgot the "fid" argument.

Note: Big-end encoding is meaningless for uint8. Big-end and little-end are only relevant when there are multiple bytes for an individual numeric value.
