I have the following pdf image generated by matlab code. When I save this image as ''pdf'', it comes up with huge white portion that I really want to remove. I just keep the image portion only. Please somebody help me to get that. Pl see the attachment for image in ''pdf''.

"I thought that as pdf image has good resolution"
Not necessarily. You can save high-resolution png and jpg files too. pdf is useful if you want vector image; however, in that case, I prefer eps over pdf.

Try exportgraphics() in R2020a
t = linspace(0, 2*pi, 100);
r = linspace(0, 1, 100);
polarplot(t, r)
exportgraphics(gcf, 'test.pdf');
The output pdf file is attached.
For older releases
t = linspace(0, 2*pi, 100);
r = linspace(0, 1, 100);
polarplot(t, r)
export_fig(gcf, 'test.pdf');
export_fig is taken from here: https://www.mathworks.com/matlabcentral/fileexchange/23629-export_fig

@Ameer: ''You can just open the fig file and while it is opened, run the code in my answer, It will work.''
Where the code has to be run? In command window or in script?

You can run it in command window or in a new script.
