Hello... Lets suppose i have a data stored in a variable
A = [1.23323 45.24343 0.1 0.001 455.34543 0.0001 ]
i want to shrink pricision of data only greator than zero... i tryed
A(A>0) - str2double(compose('%.2f',A(A>0)))
so the result should be
A = [1.23 45.24 0.1 0.001 455.34 0.0001] %% <<<< Desired Results
but its not woking, it applying %.2f on whole data....and giving >>>
A = [1.23 45.24 0.10 0.00 455.34 0.00]
Kindly Guide. Thanks

so the result should be
No, 0.001 is greater than 0, so it should have its precision reduced.

format long g
A = [1.23323 -45.24343 0.1 0.001 455.34543 -0.0001 ]
mask = A>0;
A(mask) = round(A(mask),2);
A

It is possible that what you really want is
format long g
A = [1.23323 -45.24343 0.1 0.001 455.34543 -0.0001 ]
mask = abs(A)>0.01;
A(mask) = round(A(mask),2);
A
