The input data is mint_data1. But it shows error when I run to convert cell into matrices

 coord = cell2mat(mint_data1(:,(2:3)));

Could anyone guide?

[José-Luis]

If I understand right, you are trying to convert a numeric array into a numeric array using cell2mat().

I don't see the need for the intermediary.

What is it you are trying to achieve?

[Akira Agata]

I don't see any errors in the following code. Would you tell us more details on your trouble?

% Sample cell array (100x10) with randomly located empty cells 
C = num2cell(randi(500,100,10));

% Convert C(:,2:3) into numeric array
M = cell2mat(C(:,2:3));

I have the feeling mint_data is already a matrix. What is the output of the line of code below and what is the entire error message (all the red text)?

class(mint_data1)
