Hello, when l run a code I got this error in the function code given below. I don't know where this error is.
Error using fread
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in loadDepthMap>readHeader (line 57)
numFrames = typecast(uint8(fread(fid,4)), 'uint32');
Error in loadDepthMap (line 34)
[dims, numFrames] = readHeader(fid);
code:
function [depthMap] = loadDepthMap(path)
%%READING FROM FILE
fid = fopen(path); %Assign file reading object
[dims, numFrames] = readHeader(fid);
fileData = fread(fid, 'uint32');
fclose(fid); %close the stream
depth = double(fileData); %convert to double for imaging
depthCountPerMap = prod(dims);
depthMap = cell(1,numFrames);
for i=1 : numFrames
currentDepthData = depth(1:depthCountPerMap);
depth(1:depthCountPerMap) = [];
depthMap{i} = reshape(currentDepthData, dims(1), dims(2))'; %reshape depth into matrix
end
end
function [dims,numFrames] = readHeader(fid)
numFrames = typecast(uint8(fread(fid,4)), 'uint32');
dims(1) = typecast(uint8(fread(fid,4)), 'uint32');
dims(2) = typecast(uint8(fread(fid,4)), 'uint32');
end

The error says fread is unable to get the exact file or file location. Check to it that file is existing int he given path.
