read data and plotting graph

how to read the txt file and plot the graph

[Raj]

Reading data is not a problem. Use 'fopen' to open the file and 'fscanf' to read the data. Or you can use 'textscan' to read the full file as strings and then convert numeric strings to numbers. How do you want to plot the data?

as @Raj comment it depenes of the purpose of what you need , I can for example use the command "readtable"

sound = readtable('sound.txt');% this will work if this archive is in the same matlab directory
% then you can plot (notice that I'm using the variable name Var2 since your data has no variable names)
plot(sound.Var2)
