I have a data set as attached. 6th column represent the time. I want to find the value in the 2nd Column related to "GX" in 1st column at the time "11:49:29 " I appreciate if anyone can suggest a method for this?
Thanks in advance.

fileID = fopen('text.txt');
C = textscan(fileID,'%s %s %s %s %s %s %s','Delimiter',',');
fclose(fileID);
C=[C{:}];
value=C{and(strcmp(C(:,1),'GX'),cell2mat(cellfun(@(x) ~isempty(strfind(x,'11-49-29')),C(:,6),'UniformOutput', false))),2};
disp(value)

Thanks for the answer. but when I run it there is an error called "Error using horzcat Dimensions of matrices being concatenated are not consistent. " So, I have to separate numeric values and character values as follows for the calculations.
rawNumericColumns = raw(:, [2,3,4,5,6]);
rawCellColumns = raw(:, 1);
v = rawCellColumns(:, 1);
D1 = cell2mat(rawNumericColumns(:, 1));
D2 = cell2mat(rawNumericColumns(:, 2));
D3 = cell2mat(rawNumericColumns(:, 3));
D4 = cell2mat(rawNumericColumns(:, 4));
t = cell2mat(rawNumericColumns(:, 5));
now I can not combine these all as one ( like you suggest as "C"). so, is there anyway to refer the values in numeric columns related to that character array values?
