# matrices

Scilab object, matrices in Scilab

### Description

Matrices are basic objects defined in Scilab. They can be defined as follows:

```E=[e11,e12,...,e1n;
e21,e22,...,e2n;
....
em1,em2,...,emn];```

Entries `eij` can be real or complex numbers, polynomials, rationals, strings, booleans.

Vectors are seen as matrices with one row or one column.

### Examples

```E=[1,2;3,4]
E=[%T,%F;1==1,1~=1]
s=poly(0,'s');E=[s,s^2;1,1+s]
E=[1/s,0;s,1/(s+1)]
E=['A11','A12';'A21','A22']```
