try this:

x = importdata('filename.txt'); x = regexp(x,'-?\d+\.?\d*','match'); %// detect numbers [-]a[.][bcd] x = cellfun(@str2num, vertcat(x{:})); 

if file can contain numbers in decimal form ("1.234") , in scientific notation ("1.234e-56"):

x = importdata('filename.txt'); x = regexp(x,'-?\d+\.?\d*(e-?\d+)?','match'); x = cellfun(@str2num, vertcat(x{:}));
