The NOTATION SECTION still needs pictures of how forces and displacements shall be labeled. The MATLAB TUTORIAL still needs Sparse Matrices, Formatting Output, Mfiles, Common Functions We need to site the TUTORIAL and the CLASS

Common Functions

 * Matrix Creation

The eye(m,n) command generates an identity matrix of size m-by-n. The zeros(n) command creates a n-by-n matrix with zeros and the ones command creates a matrix with ones.


 * Matrix Operation


 * Scalar


 * Vector

Here is a list of commonly used useful functions

eig  - used for eigenvalues and eigenvectors chol - for Cholesky factorization svd  - this is used for singular value decomposition inv  - this will give the inverse of a specified matrix lu   - this is for LU factorization qr   - this is for QR factorization hess - this will give the hessenberg form shur - this will provide the shur decomposition rref - this will provide the reduced row echelon form of a matrix expm - this provides the matrix exponential sqrtm - this gives the square root of a matrix poly - this will give the characteristic polynomial det  - this will give the determinant of a matrix size - returns the size of a matrix norm - provides 1- norm, 2-norm, etc. to infinity cond - condition number rank - provides rank of a matrix
