Matlab output format control%d,%f,%c,%s usage

1. %d Output integer ;

%4d That is to say The minimum total output length is 4, such as 110, Output is “_110”,“_” On behalf of the space . If 110110, The output is also 110110

2. %f Output decimals ;

%4.2f Indicative output Total length min 4, After the decimal point 2 position . If the total length before the decimal point is greater than 4, Will also output a complete 、 The right value , If before the decimal point + After the decimal point 2 Bit total length less than 4, Will be preceded by a space .

Example ：

>> a = 123456.246

a =

                123456.246



>> A_pathout = sprintf('wd_%5.1f', a)

A_pathout =

    'wd_123456.2'



>> A_pathout = sprintf('wd_%1.1f', a)

A_pathout =

    'wd_123456.2'


>> A_pathout = sprintf('wd_%10.1f', a)

A_pathout =

    'wd_  123456.2'  %%  notes ： front 2 A space 

3. %c Output string ;

4. %s Output string ;
