in this pics you see the output i want to do

i've 2 table A and B

>> size(A)

ans =

560 2

>> size(B)

ans =

188 1

i want to use array2table(A,B) to create union and later plot the table in app designer using uitable

but it gives me error

T_=array2table(A,B)

Error using array2table

Wrong number of arguments.

this error because the tables have different dimensions.. How to add blanks to the second to match lengths?

Another option might be synchronize (Synchronize Timetables)

在 MATLAB Online 中打开

If they have the same number of columns and you just want to stitch them together, one atop the other, try

AB = [A; B]

T_finally.mat

THIS IS MY SOLUTION (it's orrible...i'd like to learn the better version)

a,b,c

whos a

Name Size Bytes Class Attributes

a 560x2 69728 string

>> whos b

Name Size Bytes Class Attributes

b 188x1 3997 timetable

>> whos c

Name Size Bytes Class Attributes

c 16x1 1245 timetable

s=height(a)-height(b);
%end
s1=repmat({" "},s,2);
A=timetable2table(b);
%Acell=table2cell(A)
A.Properties.VariableNames={'Date','Prof'};
B=cell2table(s1);
B.Properties.VariableNames={'Date','Prof'};
A1=convertvars(A,{'Date','Prof'},'string');
T1=vertcat(A1,B)
%T1cell=[Acell,s1];
s=height(a)-height(c);
%end
s1=repmat({" "},s,2);
A=timetable2table(c);
A.Properties.VariableNames={'Date','Prof'};
B=cell2table(s1);
B.Properties.VariableNames={'Date','Prof'};
A1=convertvars(A,{'Date','Prof'},'string');
T2=vertcat(A1,B)
T1_=table2cell(T1);
T2_=table2cell(T2);
TT=[T,T1_,T2_]
T_finally=array2table(TT);

So is it all working now?

To stitch together horizontally you use commas and they all need to have the same number of rows.

To stitch together vertically you use semicolons and they all need to have the same number of columns. In addition, if the variables are tables, then I think the columns in the table must all have different field names.

There are a lot of "joining" table functions that may get around some of the restrictions I just mentioned above.

Sometimes it's better and easier to do stitching as regular double arrays before converting the array into a table. Just depends on exactly what you want to do (what output you want).
