To compute the Smith normal form of a symbolic matrix in MATLAB, you can use the smithForm
function from the Symbolic Math Toolbox. Here is an example implementation:
main.m136 chars7 lines
In this example, the input matrix A
is a symbolic matrix with variables x
, y
, and z
. The smithForm
function returns three matrices: B
is the Smith normal form of A
, J
is the transformation matrix that converts A
to B
, and K
is the transformation matrix that converts B
back to A
. The Smith normal form of a matrix is a diagonal matrix that represents the underlying structure of the matrix, and it can be useful for solving problems in linear algebra and other areas of mathematics.
