# how to export of a sub aera of an array to xyz?

4 次查看（过去 30 天）
if I use:
F = scatteredInterpolant(x,y,z,'natural','none');
xv=linspace(min(x,[],'all'),max(x,[],'all'),(max(x)-min(x))/faktor);
yv=linspace(min(y,[],'all'),max(y,[],'all'),(max(y)-min(y))/faktor);
zg = F({xv,yv});
and want to export an area of this array:
A=xv(1600:1:2000);
B=yv(400:1:800);
C = F({A,B});
to an xyz file....how can I manage this?
This:
fid = fopen('vdo.txt','w') ;
fprintf(fid,'%f %f %f\n', A', B', C') ;
fclose(fid) ;
or that
xx = A(:) ;
yy = B(:) ;
zz = C(:) ;
P = [xx yy zz] ;
fid = fopen('cut.dat', 'wt');
fprintf(fid, [repmat('%f\t', 1, size(P,2)-1) '%f\n'],P.');
fclose(fid)
doesn't work...
Thanks a lot

xx = A(:) ;
yy = B(:) ;
zz = C(:) ;
P = [xx yy zz] ;
fid = fopen('test.txt','w')
fprintf(fid,'%f %f %f\n', P.') ;
fclose(fid)
