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. thanks Goutham sudeep deshmukh <> wrote:Hello..!

If you have the Symbolic Math Toolbox, you can use its variableprecision 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. Sincerely, Glen Ragan
