plot missing in matlab

the problem is that when i asked to plot an audio file it gives an error on the line of the plot

Please show how you are asking to do the plotting, and show how you create the variables that you pass in to the plot call.

Answer 1

[Walter Roberson]

You cannot plot() a file by name. You need to read the data such as by using audioread(), and plot the data that results.

[Ayman Shaban]

i did that

[Ayman Shaban]

[g,fs] = audioread ('filename.wav');
sound(g,fs);
plot (g);

[Walter Roberson]

What is the error message?

Note: you should be using

t = (0:size(g,1)-1)/fs;
plot(t, g)

[Ayman Shaban]

Error in Untitled2 (line 4)

plot(t, g);

[Ayman Shaban]

i tried with definition t= but it is the same error

[Walter Roberson]

Please show the complete error message, everything that is in red.

[Ayman Shaban]

Attempt to execute SCRIPT plot as a function:

D:\apps\matlab extracted\bin\plot.m

Error in Untitled2 (line 6)

plot(t, g);

[Ayman Shaban]

thank you, i solve the problem

it was because there is a file called plot.m in matlab files
