isDone

End-of-file status for signal reader object

Syntax

isDone(src)

Description

isDone(src) returns a logical value indicating whether or not the SignalSource object, src, has reached the end of the imported signal. If the SignalEndAction property of src is set to Cyclic repetition, this method returns true every time the reader reaches the end.

Examples

Create Signal Source

Create a signal source to output one sample at a time.

src1 = dsp.SignalSource;
src1.Signal = randn(1024,1);
y1 = zeros(1024,1);
idx = 1;
while(~isDone(src1))
    y1(idx) = src1();
    idx = idx + 1;
end

Create a signal source to output vectors.

src2 = dsp.SignalSource(randn(1024,1),128);
y2 = src2(); % y2 is a 128-by-1 frame of samples
