How to import specific data in multiple tables by table2array command

The t variable is the data I want to analyze. Click on the t variable to see that multiple table files are required. And my studio wants to import all the data of row =6,8,10 column =4 in the table.

My job is as follows (mtxDISP), if you just want row=6, column=4 data, I only need table2array( t{j}(6,4) ). j is how many tables I have

But there was an error in my writing, and I don’t know how to deal with it at the moment.

clc;

Total_Ndic = num_files-1; % data points

fprintf('**** input dof position such as [6,4; 10,4; ...] **** \n');

dof_position = [6,4; 4,4; 10,4];

[m,n] = size(dof_position);

dof = m; % displacement column number

mtxDISP = zeros(Total_Ndic,dof);

for i=1:dof

for j=1:Total_Ndic

mtxDISP(j,i) = table2array( t{j}dof_position(i,:) );

end

end

fps= input('frame rates: ');

figure();

step = linspace(0,Total_Ndic,Total_Ndic);

vecTime = step./4000;

plot(vecTime,mtxDISP(:,1));

xlabel('Time (sec)')

ylabel('amplitude (pixel)')

figure();

plot(vecTime,mtxDISP(:,1));

xlabel('frames')

ylabel('amplitude (pixel)')

error :

Error using DIC_post-processingCODE (line 39)

Subscripting a table using linear indexing (one subscript) or multidimensional indexing (three or more subscripts) is not supported. Use a row subscript and a variable subscript.
