writing text files with mix of variables and strings

Hi all,
I am trying to write a text file with the following code:
% Vegetation
veg_height = 1;
veg_dens = 0.5;
stem_diam = 1;
cd_factor = 1;
% Low marsh
npts = 1;
nsec = 1;
ah = 0.16 * veg_height;
bv = 0.0027 * stem_diam;
N = 312 * veg_dens;
Cd = 0.34 * cd_factor;
C = {'npts = ' [npts];
'nsec = ' [nsec];
'ah = ' [ah];
'bv = ' [bv];
'N = ' [N];
'Cd = ' [Cd]};
D = C';
fid = fopen('lowmarsh.txt','wt');
fprintf('%s' ,D{:})
fclose(fid)
What I want is a text file called lowmarsh.txt that looks like this:
npts = 1
nsec = 1
ah = 0.16
bv = 0.0027
N = 156
Cd = 0.34
But my text files are coming out empty.
Can someone please help me to figure out what I am doing wrong?
Thank you!!
Rae

The reason your file is empty is that you forgot to supply the fid to the fprintf function, which causes it to print the text to the command window instead of the file.
% Vegetation
veg_height = 1;
veg_dens = 0.5;
stem_diam = 1;
cd_factor = 1;
% Low marsh
npts = 1;
nsec = 1;
ah = 0.16 * veg_height;
bv = 0.0027 * stem_diam;
N = 312 * veg_dens;
Cd = 0.34 * cd_factor;
C = {'npts = ' [npts];
'nsec = ' [nsec];
'ah = ' [ah];
'bv = ' [bv];
'N = ' [N];
'Cd = ' [Cd]};
D = C';
fid = fopen('lowmarsh.txt','wt');
fprintf(fid,'%s' ,D{:})
% ^^^^ add this
fclose(fid)

Hi,
Here is an example of how you can use it:
% Vegetation
veg_height = 1;
veg_dens = 0.5;
stem_diam = 1;
cd_factor = 1;
% Low marsh
npts = 1;
nsec = 1;
ah = 0.16 * veg_height;
bv = 0.0027 * stem_diam;
N = 312 * veg_dens;
Cd = 0.34 * cd_factor;
C = {'npts = ' [npts];
'nsec = ' [nsec];
'ah = ' [ah];
'bv = ' [bv];
'N = ' [N];
'Cd = ' [Cd]};
writecell(C,'lowmarsh.txt','Delimiter','tab')
