Hi All,

I would like to use my out source data (in .txt), into finding a graph. The data is b = a070_edit(:,1) are an variables that are varies along the frquecy range. The 'b' data will be used as an varible in a function to find an unknown 'a'. and then a graph will be plotted (f vs a).

Actually my equation is much more complicated. Thus below I use a simple equation, so that it will be easier to solve the problem.

`function load a070_edit.txt % list of data from outsource`

b = a070_edit(:,1) d = 1;t = 5./b;f = 50:1.5625:5600;w = 2.*pi.*f;a = (d./t).*wplot (f,a)end

Kindly, please help me to load and use an external data into matlab function.

Your help will be appreciated.

Thank you.

Regards,

Nur Arafah
