If it is only numeric data and a and b are of the same dimensions this should work:

c = a{:,:} + b{:,:}

for example:

a1 = randi(10,5,1);
a2 = randi(10,5,1);
Ta = table(a1, a2)

b1 = randi(10,5,1);
b2 = randi(10,5,1);
Tb = table(b1, b2)

c = Ta{:,:} + Tb{:,:}

gives:

Ta =

  5×2 table

    a1    a2
    __    __

    2     9 
    9     7 
    6     4 
    6     6 
    2     5 


Tb =

  5×2 table

    b1    b2
    __    __

    1      5
    3      1
    2     10
    2     10
    3      5


c =

     3    14
    12     8
     8    14
     8    16
     5    10

it's show the same problem

Undefined operator '+' for input arguments of type 'table'.

Error in Fopen (line 11)

c = a(:,:) + b(:,:);

[panakj tiwari]

this data a is 12000*1 table

and b is 12000*1 table

format this 'a' and 'b' in .mat format

[Walter Roberson]

What shows up for

A = table2array(a);
B = table2array(b);
whos A B
C = A + B;

[Walter Roberson]

By the way, consider using readmatrix() instead of readtable()

thank u sir..

%true
C = outerjoin(a,b);

Use outerjoin function
