tf = isDone(obj) returns true
when the data from a finite source has been exhausted, typically because all data has been read. The System object
obj is often a file reader, and isDone looks for the end of the file.
Otherwise, isDone returns false.
This example shows how to read a MAT file using the dsp.MatFileReader (DSP System Toolbox) object.
Note
This example requires DSP System Toolbox™.
filename = [tempname '.mat']; % Create variable name
originalData = rand(10,2);
save(filename,'originalData','-v7.3'); % Write to MAT file
mfr = dsp.MatFileReader(filename,'VariableName',...'originalData','SamplesPerFrame', 4);
while ~isDone(mfr) % Stream data into MATLAB
isDone(mfr) % Display zero if end-of-data not reached
finalData = mfr() % Display read frameend
