Attention: a default workbench was created for you

Linear Algebra Workbench

How it works: you enter your matrices and vectors, and then can perform as many calculations with them as you would like. You can enter expressions (see the form below) and they will be calculated using the linear objects that you have provided.

• Defined Objects : A , v
  
• Create (Define) New Object
• To solve a linear system Ax=v, evaluate expression inverse(A)*v, that gives you x.

Enter Expression:

Note: This form allows you to calculate expressions. These expressions can be formed from objects that you have already defined. Note that you have to enter the * sign for multiplication. This script does not understand multiplication by joining names. For instance, if you want to calculate 2*A*B*v, you have to enter 2*A*B*v, not 2ABv. You can also use the following functions: transp, inverse, det, scalar for scalar multiplication of vectors. More examples: 3*(A-C/B+D/2)*v. Also, for exponentiation, use the '^' character. For example, to calculate matrix A squared, type A^2.
