Hi,
s = load('signal.mat');
will give you a struct s containing fields with your variable(s) in it. Access this data fields with the dot-Notation:
plot(s.your_variable_name_to_plot)
should work.
EDIT:
Your file contains a numeric Matrix of size 10x20480 which appears like 10 data sets - which shall be plotted?
s = load('signal.mat');
plot(transpose(s.val))
will plot all the data in one plot:
Best regards
Stephan

My signal variable value is 1*2560 double and i tried this code to plot the signal s = load('test.mat'); val = (val - 1024)/200; signal = val(1,1:1000); Fs = 360; t = (0:length(signal)-1)/360; plot(t,signal ),grid on we can plot the signal with the above command lines.But can anybody explain about this code.
