Hi Yair

I tried to figure out how to do this, and with higher dimension cell arrays, when I was still a Matlab newbie. I was obviously ahead of myself, but with a ton of reading, testing, and asking around, I managed. But if I needed to do that again it is good to know about this function. Great tip, nice post. Thanks

In reply to Yaroslav Don. @Yaroslav - ah! makes sense, also correlates with the num2str.m code. I've updated the main text accordingly. Thanks :-)

Yair hi, After a short inspection I've come to the following conclusion: the third variable, isLeft, is used to indicate whether the output cell-string is left-justified; namely, if the '-' flag is used within the format. For example,

>> [cells, ~, isLeft] = sprintfc('%-8.5g', sqrt(2), false)
cells = 
    '1.4142  '
isLeft =
    1

however,

>> [cells, ~, isLeft] = sprintfc('%8.5g', sqrt(2), false)
cells = 
    '  1.4142'
isLeft =
    0

Sincerely, Yaroslav
