I have a for loop, but when I faced the following error, my script will stop executing. How can I do to skip the error and continue to execute the code?

Error using vertcat
Dimensions of matrices being concatenated are not consistent.
Error in ReadinData (line 160)
NonData=[Weight;Height;Age];

I have loop like this

for i = 1:100

How can I record i when the error happen, so I can check after the problem execution.

Jason - wouldn't it be better to fix the error before continuing? The error message is telling you that the dimensions of your three variables are not compatible when trying to use the vertical concatenation. When this error occurs, what are the dimensions of Weight, Height, and Age?

Thanks. I have a lot of data to read, some data may have problem, I think it is the data problem, instead of code problem, so I want to skip the data

Hi Jason,

one way would be to catch the error:

for i=1:100
  try
    NonData=[Weight;Height;Age];
    % do something with your NonData
  catch
    fprintf('Inconsistent data in iteration %s, skipped.\n', i);
  end
end
