这是外部函数:用于将棋盘的坐标更改为字母数字数据而不是纯数字。
function [] = convertIntegerToCoordinates (i)
First=floor(i/10);
if First ==1 fprintf('A')
elseif First ==5 fprintf('E')
elseif First ==6 fprintf('F')
elseif First ==7 fprintf('G')
elseif First ==8 fprintf('H')
end
Second=i-(10*First);
if Second ==1 fprintf('1')
elseif Second ==2 fprintf('2')
elseif Second ==3 fprintf('3')
elseif Second ==4 fprintf('4')
elseif Second ==5 fprintf('5')
elseif Second ==6 fprintf('6')
elseif Second ==7 fprintf('7')
elseif Second ==8 fprintf('8')
end
endfunction
2.这是主要功能:用于检测白人国王是否受到白羊,主教,女王和骑士四人威胁的功能。
function [] = ChessThreatCheck (n,b,c)
B = 'B';
R = 'R';
Q = 'Q';
K = 'K';
n= input("Please enter the coordinates of white king: ");
whiteFirst=floor(n/10);
whiteSecond=n-(10*whiteFirst);
if (whiteFirst>8 || whiteFirst<1) && (whiteSecond>8 || whiteSecond<1)
fprintf ('The x and y coordinates of the white king should be between 1 and 8\n');
return;
end
if whiteFirst>8 || whiteFirst<1
fprintf('The x coordinate of white king should be between 1 and 8\n');
elseif whiteSecond>8 || whiteSecond<1
fprintf('The y coordinate of white king should be between 1 and 8\n');
return;
end
b = input("Please enter the type of black chessman: ");
if b != B && b!= R && b!= Q && b!= K
fprintf('The type of the black chessman can be (B)ishop, (R)ook, (Q)ueen or (K)night\n');
return;
end
c = input("Please enter the coordinates of black chessman: ");
blackFirst = floor(c/10);
blackSecond = c-(10*blackFirst);
if (blackFirst<1 || blackFirst>8) && (blackSecond<1 || blackSecond>8)
fprintf('The x and y coordinates of the black chessman should be between 1 and 8\n')
return;
end
if blackFirst<1 || blackFirst>8
fprintf('The x coordinate of the black chessman should be between 1 and 8\n');
elseif blackSecond<1 || blackSecond>8
fprintf('The y coordinate of the black chessman should be between 1 and 8\n');
return;
end
if (b=='R')&&((blackFirst == whiteFirst) || (blackSecond == whiteSecond))
fprintf('The White King at %s is threatened by black rook at %s \n',convertIntegerToCoordinates(n) ,convertIntegerToCoordinates(c));
elseif fprintf('The White King at %s is not threatened by the black rook at %s \n', convertIntegerToCoordinates(n),convertIntegerToCoordinates(c));
end
return;
if (b=='B') && (abs(blackFirst-whiteFirst) == abs(blackSecond-whiteSecond))
fprintf('The white king at %s is threatened by the black bishop at %s \n', convertIntegerToCoordinates(n), convertIntegerToCoordinates(c));
elseif fprintf('The white king at %s is not threatened by the black bishop at %s \n', convertIntegerToCoordinates(n),convertIntegerToCoordinates(c));
end
if (b=='Q')&&((abs(blackFirst-whiteFirst) == abs(blackSecond-whiteSecond)) || ((blackFirst == whiteFirst) || (blackSecond == whiteSecond)))
fprintf ('The white king at %s is threatened by black queen at %s \n', convertIntegerToCoordinates(n),convertIntegerToCoordinates(c));
else if fprintf('The white king at %s is not threatened by black queen at %s\n', convertIntegerToCoordinates(n), convertIntegerToCoordinates(c));
end
if (b=='K')&& ((abs(blackFirst-whiteFirst == 2) && abs(blackSecond-whiteSecond==1)) || (abs(blackFirst-whiteFirst == 1) && abs(blackSecond-whiteSecond==2)))
fprintf('The white king at %s is threatened by black knight at %s \n', convertIntegerToCoordinates(n),convertIntegerToCoordinates(c));
elseif fprintf('The white king at %s is not threatened by black knight at %s \n', convertIntegerToCoordinates(n),convertIntegerToCoordinates(c));
end
end
输出以错误的方式打印。有人可以帮我吗? 我得到的输出是
E5E6The White King at >>
但我希望
The White king at E5 is threatened by the black rook at E6 >>
答案 0 :(得分:1)
您的问题是您的fprintf
功能已调用convertIntegerToCoordinates
。因此,该函数直接打印到主脚本中fprintf
之前的命令窗口。此外,您的函数没有输出变量,因此主脚本的fprintf
不知道要替换formatSpecs '%s'
。
这是一个更紧凑的函数版本,可以解决这个显示问题:
function out = convertIntegerToCoordinates(i)
% Get column
C = char(floor(i/10)+64);
% Get raw
R = num2str(mod(i,10));
% Output
out = [C R];
或者,相同的想法,但更紧凑:
function out = convertIntegerToCoordinates(i)
out = [char(floor(i/10)+64) num2str(mod(i,10))];
最佳,
