I have two signals represented by x and y values respectively. I have to find the convolution between the two signals. I am attaching the graph plotted from the two signals. can someone help. Thanks.

You could use the conv() function. It seems to do exactly what you want.
conv(x,y)
Please read the documentation.

numbers = xlsread(excelFullFileName);
x1 = numbers(:, 1); % x1 assumed to be in column 1.
y1 = numbers(:, 2); % y1 assumed to be in column 2.
x2 = numbers(:, 3); % x2 assumed to be in column 3.
y2 = numbers(:, 4); % y2 assumed to be in column 4.
out1 = conv(x1,y1);
out2 = conv(x2,y2);

x=[1,1,1];
y=[1,1,1];
How can I find its convolution ?

output = conv(x, y, 'full');
plot(output, 'bo-', 'LineWidth', 2);
grid on;
