Rotating 3D data

I made X, Y coordinates and a triangle with zeros and ones on this plane.
I want to rotate this triangle 45 degrees. I tried rotz(), but I don't have idea to do this.
Thanks in advance.
clc; clear all; close all;
x = linspace(-10,10,49);
y = linspace(-10,10,44);
[X,Y] = meshgrid(x,-y);
Z = zeros(44,49);
Z = importdata('triangle_rotate.txt');
imagesc(Z)

Z = importdata('triangle_rotate.txt');
subplot(121); imagesc(Z); axis equal
Z1 = imrotate(Z, 45);
subplot(122); imagesc(Z1); axis equal

You can use the crop option to keep the array the matrix the same size, but there is no guarantee the rotated object will fit inside the original borders:
Z = importdata('triangle_rotate.txt');
Z=imrotate(Z,45,'bicubic', 'crop');
