matlab's fortran's format equivalents

What would be matlab's equivalent of

write(1,'("Speed, resistance, power",3f8.2)')(a(i),i=1,3)

I've tried

a = [10. 20. 200.]
fprintf(unit1,'a = 3%8.1e',a)

but I'm still having trouble with it (the whole mat开发者_StackOverflow中文版lab output formatting thing).

Edit for Kenny: for the values of a as given above, it would give (in a new row):

Speed, resistance, power   10.00   20.00  200.00

I'm using 1 for fileID to write to the command window, and I put a newline in the end because it's prettier, but this should reproduce what you want

a = [10,20,200;20,30,300];

fprintf(1,'Speed, resistance, power%8.2f%8.2f%8.2f\n',a')

Speed, resistance, power   10.00   20.00  200.00
Speed, resistance, power   20.00   30.00  300.00

EDIT

Assume an array a of unknown dimensions. Assume further that we want to fprint it row by row

a = [10,20,200;20,30,300];

%# find number of columns
nCols = size(a,2);

%# create format string for fprintf. Use repmat to replicate the %8.2f's
fmtString = ['Speed, resistance, power',repmat('%8.2f',1,nCols),'\n'];

%# print
fprintf(1,fmtString,a')

Speed, resistance, power   10.00   20.00  200.00
Speed, resistance, power   20.00   30.00  300.00

Note: This prints all rows of a one after the other on the same line (thanks, @JS).

fprintf('Speed, resistance,power')
fprintf('%8.2f',a')
fprintf('\n')
