hi, i have the below matrix , i want each row to have only on value equal to '1' , so when searching if it find a one it will take it and make the rest values of the row equal to zero . i write the bellow code , i need to break the second loop when the if condtion is true , any one can help?
D=[ 1 1 1 1 1
1 1 1 1 1
0 0 0 0 0
0 1 0 0 0
1 1 0 1 1
0 0 1 0 0
0 0 0 0 0
0 0 1 0 0
1 0 0 1 1
0 0 0 0 0]
D = 10×5
1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 1 0 0 0 1 1 0 1 1 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 1 0 0 1 1 0 0 0 0 0
N=10;
M=5;
for n=1:N
for m=1:M
if D(n,m)==1
Dn(n,m)=1;
Dn(n,m+1:end)=0;
else Dn(n,m)=0;
end
end
end
Dn
Dn = 10×5
1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 1 0 0 0 1 1 0 1 1 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 1 0 0 1 1 0 0 0 0 0

Try using a flag
abort = false;
for n = 1 : N
for m = 1 : M
if conditionForBreaking
abort = true; % Set flag
break; % Exit inner loop.
end
end
if abort
break % exit outer loop.
end
end

Using Matlabs "continue" command should do what you need.
