How to print an integration of double and string data?

Hi

How can I print the following matrix without using table in the command window?

NONE FX NLM TV

SSIM 0.9 0.97 0.99

SNR 2 4 5

You can use fprintf() and a loop, and you get simple code.

Or you can use some fancy tricks involving putting all of the data into individual cells of a 2D cell array, and transposing the cell array so that the columns become rows,

temp = [{'SSIM'} {'SNR'}
        {0.9}    {2}
        {0.97}   {4}
        {0.99}   {5}]

and then

fprintf('%5s %5g %5g %5g\n', temp{:});

which would internally expand to

fprintf('%5s %5g %5g %5g\n', 'SSIM', 0.9, 0.97, 0.99, 'SNR', 2, 4, 5);

So it is possible to output mixed data with consistent formats using fprintf() in vectorized form... it just isn't pretty.

A cleaner approach is to use compose() and strjoin() the result: compose has the nice property of working row by row instead of column by column.
