applyMatrix(float [4][4] Matrix) saveMatrix...

hellow
is there any easy and quite fast way to
save, load and apply OpenGL scene matrix.

I know there is pushMatrix, popMatrix, and
applyMatrix( float, float, float, float ......), however

I'd like something I can use to store and restore the matrix as I need.
Something to store it and restore from data structure in RAM which I can edit and control.
like

float [][] MyMatrix1 = new float[4][4];
MyMatrix1 = saveMatrix();
MyMatrix1[1][3]+=0.15665;
loadMatrix(MyMatrix1);

aha, OK, It§s writen in references

my problem solve
float[] Fs = new float[16];
PMatrix MyMatrixCopy = getMatrix();
MyMatrixCopy.get(Fs);
float[7]=0.15665;
MyMatrixCopy.set(Fs);
setMatrix(MyMatrixCopy);

but it's quite cumersome
is there a way how to acces to scene transform matrix direcly?

Like just get reference (pointer) to the transform matrix of scene or better to array of its values?
