a070_edit.txt

在 MATLAB Online 中打开

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).*w
plot (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

B % just call it
function B % not if the file is input from outside the function then parameterize you function by providing an input for it
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).*w;
plot(f,a)
end
