I am attaching the file which contains the coordinates of a polygon. I want to split the data given in the attached file into x and y variables. For example:
x=[1,1,2,2,1,NaN,4,4,5,5,4,NaN,6,6,7] and
y=[1,1,2,2,1,NaN,4,4,5,5,4,NaN,6,6,7]
How can i split my data into this format. Please do answer my question. Thank you

it's very unclear what you're asking particularly as there's no value in your demo matrix that belongs to the set [1,1,2,2,1,NaN,4,4,5,5,4,NaN,6,6,7].
In view that your cell array contains exclusively, N x 2 matrices, I'll assume that you just want to concatenate the whole lot. Use vertcat together with expension of cell array into comma separated lists:
load('trialdataofcoordinates.mat');
coords = vertcat(mycoordinates{:});
x = coords(:, 1)
y = coords(:, 2)

The simplest way is to add a row of 1x2 matrices of NaN to your cell array. The reshaping into a single column (with the : operation) will automatically place the NaN matrix in between each other matrices:
load('trialdataofcoordinates.mat');
mycoordinates(2, :) = {[nan nan]};
coords = vertcat(mycoordinates{:});
x = coords(:, 1)
y = coords(:, 2)
