How to compare two variables data by using ifelse? if both variable contain same number and length of data, so condition becomes true it should perform desired functionality.

i want to establish a logic that if variable data is same as variable data "a" or "b'' or "c" or "d"then it should perform the listed functionality
i was trying the below code to get second elseif true and answer "Value==2" but when it first compare if data == a... it gives error >>>Matrix Dimension Must Agree"
a = -6:6;
b = -3:3;
c = 0:6;
d = 0:12;
% data = [-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6] % user selected
data = [-3 -2 -1 0 1 2 3] % For this Data condition "Value = 2" should be answer
% data = [0 1 2 3 4 5 6]
% data = [0 1 2 3 4 5 6 7 8 9 10 11 12]
if data == a
value =1
elseif data == b
value = 2
elseif data == c
value = 3
elseif data == d
value = 4
end
it is giving error that "Matrix Dimesions Must Agree"

If you only plot when 'b' and 'c' are equal to 'a', then are you trying to plot(a, a).

Read about isequal.
a = -6:6;
b = -3:3;
c = 0:6;
d = 0:12;
% data = [-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6] % user selected
data = [-3 -2 -1 0 1 2 3] % For this Data condition "Value = 2" should be answer
% data = [0 1 2 3 4 5 6]
% data = [0 1 2 3 4 5 6 7 8 9 10 11 12]
if isequal(data,a)
value =1
elseif isequal(data,b)
value = 2
elseif isequal(data,c)
value = 3
elseif isequal(data,d)
value = 4
end
But what you are trying to do.....what you are doing is not fine.

data and a,b,c,d have different dimensions. Use isequal()
if isequal(data, a)
value =1
elseif isequal(data, b)
value = 2
elseif isequal(data, c)
value = 3
elseif isequal(data, d)
value = 4
end
Or the following more general approach
a = -6:6;
b = -3:3;
c = 0:6;
d = 0:12;
data = [-3 -2 -1 0 1 2 3]; % For this Data condition "Value = 2" should be answer
C = {a, b, c, d};
value = find(cellfun(@(x) isequal(data, x), C));
