What is the solution to this error?

I am working on object detection, when I execute the code, I have errors. It is a ready code, I put the dataset in the same folder with the files code, also DefaultRoot.mat and CAfilelist.mat exists in the same folder.

But, I have this error:

>> SSDBExperiment_BuildCropDataset

Undefined function or variable 'DefaultRoot'.

Error in SSDBExperiment_BuildCropDataset (line 7)

D.Root =DefaultRoot;

.............................................................................

here a part of code,(SSDBExperiment_BuildCropDataset)

..............................................................................

negative image

What should I do, which lines need change to work correctly.

Thank you in advanced.

You are trying to use a function or variable in your code that has not been defined or is not accessible. Double check the contents of your DefaultRoot.mat file. It appears to not contain a variable named DefaultRoot.

The error is easy enough to demonstrate by trying to use a variable that has not been created.

A = 1;
% Works
B=A

B = 1

% Your error
b=a

Unrecognized function or variable 'a'.

DefaultRoot=load('DefaultRoot.mat'); %-->DefaultRoot

D.Root =DefaultRoot;

it works.
