matlab问题

    for j=1:n

for i=1:m
if Checkseed(i,j)==0
outPutlmgRed(i,j)=ColorRed(i,j);
outPutlmgGreen(i,j)=ColorGreen(i,j);
outPutlmgBlue(i,j)=ColorBlue(i,j);
Checkseed(i,j)=1;
check8Pixel=zeros(m,n);
check8Pixel(i,j)=1;
f=check(check8Pixel);
while f
for colcol=colleft:colright
for rowrow=rowup:rowbottom
if check8Pixel(rowrow,colcol)==1
if rowrow-1>0&rowrow-1<=m &colcol-1>0&colcol-l<=n
if Checkseed(rowrow-1,colcol-1)==0
if sqrt((ColorRed(rowrow-1,colcol-1)-ColorRed(i,j))^2+(ColorGreen(rowrow-1,colcol-1)-ColorGreen(i,j))^2+(ColorBlue(rowrow-1,colcol-1)-ColorBlue(i,j))-2)<=Threshold;
Cheekseed(rowrow-1,colcol-1)=1;
outPutlmgRed(rowrow-1,colcol-1)=ColorRed(i,j);
outPutlmgGreen(rowrow-1,colcol-1)=ColorGreen(i,j);
OutPutlmgBlue(rowrow-1,co1col-1)=Co10rBlue(i,j);
