Angles to arrow representation

I have attached an Excel sheet which includes angles ranging from 0-90 degrees. I want the arrow representation for those values.

Thank you.

You need to have radius along with theta. Than you can use quiver to plot the arrows.

data=xlsread('New Microsoft Excel Worksheet.xlsx');
l=0.5; % Length of the arrow
for i=1:6
    for j=1:6
     angle=data(i,j);
     u=l*cos(angle); % convert polar (theta,r) to cartesian
     v=l* sin(angle);
     quiver(i,j,u,v,'linewidth',1.5);
     hold on;
    end 
end
grid on;

May be other smart ways also to do the same
