On matlab n queen problem-CodePudding

Today in an attempt to use matlab to solve the n queens problem, but the output of the board the result is always wrong, looked at half a day also don't see what's the problem, help you a great god help solve, thank you!
The code below
The input for the queen (zeros (m), m, 1)
M is the board size, the layer is to control the number of rows

 function queen (map, m, layer) 

If the sum (the sum (map))==m % recursion end condition 
Disp (map); 
% count also can't write 
Return 
End 

For I=1: m % in each row of each position to try to put queen 
If layer==1% the first line does not need to determine whether can put 
The map (layer, I)=1; 
Queen (map, m, layer + 1); 
Elseif layer> 1 

% to determine if I can put a 

% to judge whether the column has been queen 
Temp1=0; 
For row=1: I 
If the map (the row, I)==1 
Temp1=temp1 + 1; 
End 
End 

% judgment have upper left diagonally queen 
Temp2=0; 
K1=layer - 1; 
If I & gt; 1 
For left=I - 1 
If k1 & gt;=1 & amp; & The map (k1, left)==1 
Temp2=temp2 + 1; 
Elseif k1 & lt; 1 
Break 
End 
K1=k1-1; 
End 
End 

% judgment right diagonally 
Temp3=0; 
K2=layer - 1; 
If iFor the right=I + 1: m 
If k2 & lt; 1 
Break 
Elseif k2 & gt;=1 & amp; & The map (k2, right)==1 
Temp3=temp3 + 1; 
End 
K2=k2-1; 
End 
End 

% if can put, iterative 
If temp1==0 & amp; & Temp2==0 & amp; & Temp3==0 
The map (layer, I)=1; 
Queen (map, m, layer + 1); % to the next line began to put queen 
The map (layer, I)=0; 
End 
End 
End
