Load .mat file

After many hours trying to figure out how to load a file, I finally gave up ! It's my first time to use Load command, So please give me a basic explanation I have tried to load a file by the following code:

load pulse_7cm_-14dB_10x_aver;
t  =  Ts:Ts:size(RF)*Ts;
subplot(2,2,1);
plot(1e6*t,1e3*RF);
xlabel('time [\mus]');ylabel('Voltage [mV]');title('T');

but this error appears:

Error in ==> wer at 1
load pulse_7cm_-14dB_10x_aver;

What is the problem?

check that current directory contains your file to load - if yes, try this (use an extensioni, if exists):

load('pulse_7cm_-14dB_10x_aver.wav') % ssumed that this is a WAV file

you may look on handy function uigetfile (here is documentation )
