Hello,
I am new to Matlab and am trying to figure out which is more accurate:
If I am inverting a Matrix and want to express it in the most accurate fraction form, does the format sym or the format rat work better?
When I invert both, my inverse matrix shows up as fractions (which is what I need), but the matrices are different, assuming something to do with roundoff. Which is a more standard solution? T
Thank you!

'sym' is to represent as symbolic constant and 'rat' does the approximation, if you dont want to approximate in the between and deviate from the actual result use rat at the end, for more detailed explaination refer the doument here.
