Increasing precision in Matlab

Started by sudeep deshmukh January 31, 2003
Hello..!

I had a question regarding , how to increase the accuracy of Matlab
to any desired number of digits after the decimal point in the case where the
eigen values and eigen vectors...

Also , I would like to know in general how to improve the accuracy so that
matlab shows values upto a specific number of decimal places in any mathamatical
operation.

Thanks,

Sudeep



Hi Sudeep Deshmukh
Try looking for a command "Format" in MATLAB help menu. I hope this solves
your question.

If you have the Symbolic Math Toolbox, you can use its variable-precision
arithmetic (VPA) to accomplish what you want. Of course, eventually you would
need to be concerned about the precision available on your input data, but the
computations you perform can be done to any precision you wish.

Most Matlab functions cannot be used with VPA, but basic matrix manipulations
and basic arithmetic operations can.
