Hi,

I am trying to round the matrix to 2 decimal places a=[1.232323 2.23232323; 3.23232323 4.2323232332] round(a,2)

I am getting the error too many input arguments. Is there a work around?

You can create your own version of the ‘new’ round:

roundn = @(x,n) round(x*10^n)./10^n;
q = roundn(pi,2)
q =
         3.14

Is there no way to round and truncate maybe the numbers?

Found it!!!

after rounding, convert num2cell and then use

fun3 = @(x) sprintf('%0.3f', x);
