一、MATLAB
1.1 floor函数
Y = floor(X)
rounds each element of X to the nearest integer less than or equal to that element
1.2 矩阵
x=house
house 函数
function X = house
% HOUSE Outline of a house.
% H = house;
% dot2dot(H)
% wiggle(H)
&X = [ -6 -6 -7 0 7 6 6 -3 -3 0 0
-7 2 1 8 1 2 -7 -7 -2 -2 -7 ];
dot2dot(x)
dot2dot 函数
function dot2dot(X)
% DOT2DOT Connect the points from a 2-by-n matrix.
X(:,end+1) = X(:,1);
plot(X(1,:),X(2,:),'.-','markersize',18,'linewidth',2)
axis(10*[-1 1 -1 1])
axis square
