matrix brush

matrix brush(id)

         Returnsthe la matrix of brush id.

matrix brush(id)={mi,j} 0 < =i,j < np

         Assigns this matrix.
Note:
defines a convolution matrix if the brush if of type smooth or average.

matrix quat

matrix quat(a,x,y,z)

         Returns the matrix 4*4 of the quaternion defined by angle a and axis (x,y,z).
Examples:
m=matrix quat(0,0,0,0);edit(m)format(4);
Imprime:
1 0 0 0
0 1 0 0
0 0 1 0
0 0 0 1
m=matrix quat(.25*PI,0,0,1)edit(m)format(4);
Prints:
-1.000000 -1.570796 0.000000 0.000000
1.570796 -1.000000 0.000000 0.000000
0.000000 0.000000 1.000000 0.000000
0.000000 0.000000 0.000000 1.000000

matrix network

matrix network(id)

Returns the matrix of the synaptic weighs of the neural network id.

matrix network(id)=p11,p12,...,p21,p22,...,pn1,pn2,...,pnn

         pij is the matrix of synaptic weights of the network id.
Note: This matrix is the square array m [n, n] (n = number of neurons), m [i, j] = weight of the connection between neuron i and neuron j.

matrix transformation

matrix unit

         Returns the unit matrix.

matrix dila(cx,cy,cz)

         Returns the dilatation matrix coefficients (cx,cy,cz).

matrix dilx(c)

         Returns the x dilatation matrix coefficient (c).

matrix dily(c)

         Returns the y dilatation matrix coefficient (c).

matriz dilz(c)

         Returns the z dilatation matrix coefficient (c).

matrix hom(c)

         Returns the dilatation matrix coefficient (c,c,c).

matrix rotx(a)

         Returns the x rotation matrix angle (a).

matrix roty(a)

         Returns the y rotation matrix angle (a).

matrix rotz(a)

         Returns the z rotation matrix angle (a).

matrix syma

         Returns the symmetry matrix.

matrix symx

         Returns the x symmetry matrix.

matrix symy

         Returns the y symmetry matrix.

matrix symz

         Returns the z symmetry matrix.

matrix vol

matrix vol(id)

         Returns the matrix 4 * 4 of volume id in homogenous coordinates.
