MATLAB: Fprintf %f

%f fprintf

I have an fprintf command

fprintf('\n %s \n%0.3f',Data{:})

where my data contains a sentence and then an array. I want the decimal places for the array to only go to 3 which seems only work for every other number. So every thing comes out fine but it looks like this:

Sentence

1.784

2.862691e+000

2.737

2.855501e+000

2.976

i dont want the exponentials

Your format specifier string expects Data to have the form "string number string number string number etc." Apparently Data{1} is a string but I'm not sure Data{3} and Data{5} are. They're probably numbers, not strings, so when it tries to print those numbers out as strings (according to %s) you get the unexpected results. Show us how you constructed Data.

Make Data like this:

Data={'The calculated means for ERP0 are ','The standard deviations for ERP0 are ', 'The calculated means for ERP08 ', 'The standard deviations for ERP08 are '; mean0 stdev0 mean08 std08}

Notice the ";" instead of ",". The point is to make Data a 2x4 cell array rather than 1x8 array, then the fprintf() code you have should get what you want.

format_data = '%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f%6.3f';
format_data = strrep(format_data,'%',' %');
format_data(1) = '';
