I keep getting the above error with my code, i am trying to use the pcolor funtion to plot cell dominance, from z which is a 546x1 double.
x1 = 1:26;
y1 = 1:21;
[X1,Y1] = meshgrid(x1,y1);
z = Ind(:,1);
i = pcolor(x1, y1, z);

h = pcolor(X1, Y1, z); % use X1, Y1 instead of x1 , y1, z must be 21x26 matrix

x1 = 1:26;
y1 = 1:21;
[X1,Y1] = meshgrid(x1,y1);
z = rand(21,26)
