I guess your format of matrix in .mat file is wrong. In the matrix, the time stamps should be in first row and the data with respect to each time stamp should start from second row.

Try this:

A = textscan(fid, '%s', 'Delimiter', ' ');
impData = A{1};  %%This cell contains your data
impData = impData (3:end); %%The data excluding the first two lines
strData = cellfun(@strsplit, impData, 'UniformOutput',0); %%Split data into two rows
numData = cellfun(@str2double, strData, 'UniformOutput',0); %%Convert to numeric values
matData = cell2mat(numData); %%Convert into a matrix
