matlab runing problem(libmwlapack.dll missing)

i have a problem to run matlab software matlab r2013a, when me open this its give the error+ "libmwlapack.dll" files missing in your systemm...now i can resolve this issuee?

Someone I know had this problem today. He is a user of "avast" anti virus which (very probably wrongfully) flagged this file as containing a virus and therefore contained it.

Restoring the file through avast's interface (and telling avast to behave) solved the problem.

how can i solve this by Avast interface

[Markus]

I do not know exactly how it looks like but search for the "virus chest" where the file should be contained. Maybe this blog entry helps you.

thanks .its works good..thank you

i have another problem can you tell me about it

my project is "feature based face detection and recognition" me complete the detection part (detect the face from an image on the bases of skin color).now i want to applyy code for recognition using PCA of that detected face me have code

is it right?or me can use for my project. me need the information about that person which recognizeed.. how i can embed it with my coding?enter image description here

this is detected phase which me compelete now tell mee how i can compelte recognition phase using PCA?

Same here with R2013b, allready tried to reinstall but it didn't solve the problem.

Yesterday everything was just working fine ???
