Please help me shorten my code..

Question

Hey guys,

My question is to shorten repeating the process.

Data1=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[31 1 286 255]);

Data2=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[299 1 554 255]);

Data3=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[567 1 822 255]);

Data4=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[835 1 1090 255]);

Data5=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[1103 1 1358 255]);

Data6=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[1371 1 1626 255]);

Data7=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[1639 1 1894 255]);

Data8=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[1907 1 2162 255]);

Data9=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[2175 1 2430 255]);

Data10=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[2443 1 2698 255]);

Data11=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[2711 1 2966 255]);

Data12=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[2979 1 3234 255]);

Data13=dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t',[3247 1 3502 255]);

where the first 30 lines must be skipped before obtaining Data1. After Data1, 12 lines must be ignored for Data2 - Data13. Each data contains 256*255 matrix.

Note: dlmread('myfile.txt', '\t', [R1 C1 R2 C2]);

I would be really greatful for all your helps. Thank you.

Answer 1

you could use a loop and collect your data sets in a cell array, something like (not tested)

nData = 13;

data = cell(nData,1);

for n = 1:nData
    startPos = 31+(n-1)*268;
    endPos = 286 + (n-1)*268;

    data{n} = dlmread('BadgCk-20001103-RZhS-1hAccumx10-TextData0-1.txt','\t', [startPos 1 endPos 255]);
end

edit: if you want combine all the data to one large matrix afterwards, you can use

dataMatrix = [data{:}]

you may need to transpose the result of dlmread first depending on how you want to concatenate into the final matrix
