Hi,

I intend to read data from the .dat file. Here each data set is sperated by '&', so if I use below script, it just reads only the first eight rows. However, I need to read the entire data stored in the .dat file.

B=importdata('test.dat');

Output data = B.data;

在 MATLAB Online 中打开

test.zip

fn = unzip('test.zip')
fn = 1×1 cell array
    {'test.dat'}
T = readtable('test.dat','FileType','text','Delimiter','\t','MultipleDelimsAsOne',true)
Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.
