Lol Walter sorry for all these questions. I figured it myself though
used
NAME = [Path_Name,File_Name];
struct=load(NAME);
structnames = fieldnames(struct, '-full');fiields in the struct
k=length(structnames);
for i=1:k
namevar=strcat('struct.',structnames{i});
value=eval(namevar);
assignin('base',structnames{i},value);
end
Now my only problem is how to make a large gui record sound from the microphone and play it after i apply some filters to it. But thats another story

The eval is totally unneeded.

Hi everyone ,
i am new in MATLAB , and i have done my project in it and now i need to create a GUI for my project.
using the GUI , i should be able to have the following things : in my project i have 2 different channels with their results. ( AWGN , BEC )
in each channel for example : AWGN , i have different SNR from 0.5 till 3.5.
in each value of the SNR , i have different code length values like : ( 8,16,32,64,128,256,512,1024,2048)
for each code length i have stored results .MAT file , in that file i need to extract a variable called indeces(order of numbers) , and then do some calculation ( show the first 10% , 20% , 30% ...100% of that variable indeces in a txt.file.
so the main idea is : select the channel type , select the SNR values , select the CODE LENGTH , choose the percentage , after that show the results in a .txt file so how to link all the above options together with the right results file. your help is appreciated and helpful...
Regards
