introducing a specified indent in the output text file

I am trying to introduce in a specified indent in fprintf ...to get a certain output of the file. \t was not a big help, it was giving a tab from the string before it..and in every line the strings are of different length.

output:

 lat_to_long_tread_stiffn_ratio  =    0.995941                   $ -
 sidewall_to_tread_stiffn_ratio  =    0.1                   $ -
 damping_tread_rubber  =          3.33e-05                   $ s

desired output:

 lat_to_long_tread_stiffn_ratio =  0.995941               $ -
 sidewall_to_tread_stiffn_ratio =  0.1                    $ -
 damping_tread_rubber =            3.33e-05               $ s

 max_friction_velocity =           14.1877                $ mm/s
 sliding_velocity =                149.718                $ mm/s
 blocking_velocity =               19623.8                $ mm/s
 low_ground_pressure =             0                      $ bar

If you provide the input data, it is easier to create an answer.

fprintf('%31s= %23.6f $ %s\n', 'lat_to_long_tread_stiffn_ratio', 0.995941, '-');

the input is consists of various cells, generated from textscan, to read in the original file. I have to modify few of the values. So:

breakdown = textscan(fid,'%s%s%s','delimiter',{'=','$'});

and to print i am doing :

for idx = 1 : length(breakdown{1,1})

fprintf(fid1,' %s =\t\t\t\t\t\t%s\t\t$ %s\n',breakdown{1,1}{idx},breakdown{1,2}{idx},breakdown{1,3}{idx});                 

end

thanks for your inputs

thanks a lot for your answer. it sort of works but I want the 1st char values to start from the same place as well. So it should be:

lat_to_long_tread_stiffn_ratio =  0.995941               $ -
max_friction_velocity =           14.1877                $ mm/s

but what i am getting is:

lat_to_long_tread_stiffn_ratio =  0.995941               $ -
         max_friction_velocity =  14.1877                $ mm/s
