A matrix of symbolic elements is reasonably useful for many analytic linear algebra applications, and for analytic vector, matrix and tensor differentiation.
This function produces a matrix of arbitrary dimension of symbolic elements that are indexed by their position in the symbolic matrix for ease of reference.
>> M = symMat([2 2],'m','real')
[ m11, m12]
[ m21, m22]
m11*m22 - m12*m21

An update has been made such that the element indexing conforms to standard matrix notation: i.e., e153 is now the element of row 1, column 5, layer 3.
