MATLAB: To assign to or create a variable in a table, the number of rows must match the height of the table

Question

I´m trying to train a fast RCNN, but when i put this code:

>> load ('Tdata.mat');
>> Labeldata=Tdata; 
>> Labeldata.imageFilename=fullfile('C:\Users\JV\Desktop\Labeldata.imageFilename'); 

i get this error: To assign to or create a variable in a table, the number of rows must match the height of the table.

The number of images that i have in that file is 6,808 and the height of my table "Tdata" is the samePlease, any help, i don´t know what to do!!

Answer 1

You wrote a literal string instead of concatenating the variable data onto the end of the character vector.

fullfile('C:\Users\JV\Desktop\Labeldata.imageFilename')
%                             ^^^^^^^^^^^^^^^^^^^^^^^^ part of literal character vector, NOT a variable!
%        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ one character vector.
%^^^^^^^^ does nothing

You probably meant to do something like this:

Labeldata.imageFilename = fullfile('C:\Users\JV\Desktop',Labeldata.imageFilename);
