How to change the output file name with the same input file name but with a different extension ?

조회 수: 19(최근 30일)
In line 1, I have read all files with .nc extension. And in the last fourth line, I want to save the output file with the same name but with different extension. For eg. If the input file name is 'BOB_LEHAR_CS_2013112718_TRMM.nc' then i want to save the output file as 'BOB_LEHAR_CS_2013112718_TRMM.grd' How to do this. Please help me.
File= dir('*.nc');
for j =1:2
dx= 10
radius= 600
lon=ncread(File(j).name,'lon');
lat=ncread(File(j).name,'lat') ;
rain=ncread(File(j).name,'rf');
rain=rain(:,:,1);
for i =1: radius/dx
i=i*dx
A=cyclonic(0,0,1,i,lat,lon,rain);
B(:,i/dx)=A(:,4);
end
B1=B(1:360,:);
fpo=fopen(sprintf('file%i.grd',j),'wb');
fwrite(fpo,B1,'float32');
fclose(fpo);
end

Use fileparts to get the filename without the extension:
>> old = 'BOB_LEHAR_CS_2013112718_TRMM.nc';
>> [~,name] = fileparts(old);
>> new = sprintf('%s.grd',name)
new = BOB_LEHAR_CS_2013112718_TRMM.grd

old = 'BOB_LEHAR_CS_2013112718_TRMM.nc';
new = regexprep(old, '\.[^.]+$', '.grd')
