For Command Window and ‘tooltip’ formatting, use:
format short eng
or:
format long eng
For printed output (using fprintf or sprintf), I wrote a little utility anonymous function for my own use to do that:
engntn = @(x) [x*10.^(-3*floor(log10(abs(x))/3)) 3*floor(log10(abs(x))/3)]; % Engineering Notation Mantissa & Exponent
Result2 = sprintf('%.4fE%+04d', engntn(Q1))
for example:
Q1 =
143903542.580052
Result2 =
'143.9035E+006'
