## Play Audio file from Maple...

Maple

I performed the following procedure to simulate the function of Matlab soundsc(Scale data and play as sound).

N := 16000;
t := Vector(N, i-> evalf(2*i/(N-1)) end proc);

sound1 := sin~((2*evalf(Pi)*440)*t);

aud := Create(sound1, duration = 10.0);

PlayWave := proc (data, SampleFreq)
local SoundFile;
setattribute(data, SampleFreq, 16, 1);
SoundFile := "Bflat3.wav";
Write(SoundFile, data);
process[launch](cat("sndrec32.exe ", SoundFile))

## unwrapped phase procedure...

Maple

how to implement the unwrap function from Matlab?

Description

Q = unwrap(P) corrects the radian phase angles in a vector P by adding multiples of when absolute jumps between consecutive elements of P are greater than or equal to the default jump tolerance of radians. If P is a matrix, unwrap operates columnwise. If P is a multidimensional array, unwrap operates on the first nonsingleton dimension.

## How to Plotting Matrix 8 × 8 matrix...

Maple

How to Plotting Matrix  8 × 8 matrix:

0, 0, 0, 0, 0, 0, 0, 0
0, 1, 1, 1, 1, 1, 1, 0
0, 1, 0, 0, 0, 0, 1, 0
0, 1, 0, 1, 1, 0, 1, 0
0, 1, 0, 0, 0, 0, 1, 0
0, 1, 0, 0, 0, 0, 1, 0
0, 1, 1, 1, 1, 1, 1, 0
0, 0, 0, 0, 0, 0, 0, 0

This matrix would correspond to the following image where 0=black and 1=white.
