%hi,
%how to plot rectangles from csv files? This code does read the csv file
Array=csvread('dataxyz.csv');
n = Array(:, 1);
m = Array(:, 2);
plot(m, n)
%but it doesnt work
c = [n m];disp(c);
pos = [c-R*0.5 R R];
r = rectangle('Position',pos,'Curvature',[1 1], 'FaceColor', 'black', 'Edgecolor','none')
%thankyou

Each call to rectangle() draws exactly one rectangle. You cannot get rectangle to draw multiple rectangles in a single call.
Hint:
x = [x1 x2 x2 x1 x1 nan x3 x4 x4 x3 x3 nan ...]
y = [y1 y1 y2 y2 y1 nan y3 y3 y4 y4 y3 nan ...]
plot(x, y)

A = [1 31
4 9
12 56
17 12
47 43
56 45
43 25
50 14] ;
R = 1 ;
th = linspace(0,2*pi) ;
x = R*cos(th) ;
y = R*sin(th) ;
figure
hold on
for i = 1:size(A,1)
xc = A(i,1)+x ;
yc = A(i,2)+y ;
plot(xc,yc) ;
end
