whos -file matlab_Tab.mat       % see what is in the .mat file first

  Name      Size            Bytes  Class    Attributes

  Tab        -              41077  table              

tab=load('matlab_Tab.mat');
tab                             % show it

tab = struct with fields:
    Tab: [387x12 table]

tTab=tab.Tab; clear tab         % somehow a table was saved into a struct; return it to the table
head(tTab)                      % show the content...

The function form of load returns the content of a .mat file as a struct with the variable names as fieldnames in the structure. In this case that turned the table, tab into a filed in the new tab variable.

The above gest the table back programmatically, the easier solution is to use the command form of load instead...

clear               % remove everything so far so start clean...
load matlab_Tab
whos

  Name        Size            Bytes  Class    Attributes

  Tab       387x12            41077  table              

head(Tab)

Now one has the original table without any unecessary machinations to get to it...

Now the question becomes one of what the

find(mod(tab.Tab,1)~=0);

command was intended to do?

[shamal]

hi, I already solved it by writing

gg=table2array(Tab);

gg1=find(mod(gg,1)~=0);

if gg1

msgbox('Ci sono decimali..correggerli')

return;

end
