This fuction performs backward adaptive quantisation of the input vector x It returns the quantised signal yb, the quantised index ind for each sample of yb and the quantiser step size ss used for each sample of yb The algorithm commences wi

[ya,ind,sd]=FA_quant(x,l) This fuction performs Forward adaptive quantisation of the input vector x using the block size specified in l It returns the quantised signal ya, the quantised index ind for each sample of ya and the quantiser
