How to save "char" datatype column data into the NetCDF file along with "int32", "single", and ''double" datatype column data?

I have "int32", "single", ''double" and "char" datatype of column data in the attached mat format file (26.8 kb). I want to save all the data into a NetCDF file without changing the size of other variables. But I am getting errors until I am not making the size equal to the variable. Can someone tell me how to put the following four variables into ncfile?

load('gdp_hourly_velocities_f86e_04a9_23f1.mat')

ld1=gdp_hourly_velocities.drogue_lost_date;

lt1=gdp_hourly_velocities.latitude;

rw1=gdp_hourly_velocities.rowsize;

st1=gdp_hourly_velocities.DeploymentStatus;

nccreate('ncfile.nc','ld1','Dimensions',{'ld1',1,size(ld1,1)},'Datatype','double');

ncwrite('ncfile.nc','ld1',ld1);

nccreate('ncfile.nc','lt1','Dimensions',{'lt1',1,size(lt1,1)},'Datatype','single');

ncwrite('ncfile.nc','lt1',lt1);

nccreate('ncfile.nc','rw1','Dimensions',{'rw1',1,size(rw1,1)},'Datatype','int32');

ncwrite('ncfile.nc','rw1',rw1);

nccreate('ncfile.nc','st1','Dimensions',{'st1',4,size(st1,1)},'Datatype','char');

ncwrite('ncfile.nc','st1',st1);
