this is my raw data file.

I have 10,000 raw data file and i'd like to make a histogram with this data.

I tried //histogram(my_file.raw)// but it doesn't work. the error message is my data is complx, instead function need real data.

to sum it up,

I'd like to know how to import my raw data to my matlab variable and how to make a histogram with my complex raw data.

Thank you very much.

I recommend that you read the help for load and for importdata, and try the examples provided.

histogram(x) does not work with complex x. A histogram of complex data would be a 3D plot.

You can do

histogram(real(x))
histogram(imag(x))
histogram(abs(x));

There are functions to make a histogram of complex data, in the Matlab File Exchange, such as this package.

Good luck.
