[R] specific matrix element tranformation

[bantex]

Hi guys,

I am trying to write a function that allows me to perform specific
transformations to each element of 
a 2 by 2 matrix to generate a 3 by 3 matrix. 

Input into function-2 by 2 matrix
Output from function -3 by 3 matrix

For example: 
# a is my original 2 by 2 matrix
#b is my new 3 by 3 matrix

set.seed(2)
a=matrix(rnorm(4),ncol=2)

#let's say these are the transformations i wish to perform 
b[1,1]=a[1,1]+1
b[1,2]=a[2,1]*a[2,2]
b[1,3]=a[2,2]+a[1,1]
b[2,1]=a[1,1]-5
b[2,2]=sqrt(a[2,2])
b[2,3]=a[1,1]/a[2,2]
b[3,1]=a[2,2]-3
b[3,2]=a[1,1]*[a[1,2]+a[2,2])
b[3,3]=sqrt(a[1,1])/a[1,2])


Thanks.

Cheers,
B
