# MATLAB: String to Variable once more

string to variable

Hello,
I am having hard time following a generic code for this. So I will put my own code in and see if anyone can help me: …
Columns={'A';'B';'C';'D';'E';'F';'G';'H';'I';'J';'K';'L';'M';'N'};
Rows={'2';'31';'61';'91';'121';'151';'181';'211'};
Labels={'0';'01';'02';'04';'08';'16';'24';'36';'50';'625';'75';'875';'1';'1125'};
for i=1:14;
    Var1=strcat('Rand',Labels(i,1));    Var2=strcat('Delta',Labels(i,1));    C1=strcat(Columns(i,1),Rows(j,1));if exist(Var1{1,1},'var')==1 && exist(Var2{1,1},'var')==1xlswrite(filePattern4,genvarname(Var1{1,1}),'Sheet1',C1{1,1});xlswrite(filePattern4,genvarname(Var2{1,1}),'Sheet2',C1{1,1});endend
The variables Rand0, Rand01, etc. are defined at the beginning of the code but they are case dependent so some of them are not always there. That is why I use exist. I thought genvarname would work to convert string into variable but it didn't. Could anyone help with this? Thank you!
