4D plot in Matlab

I have x,y,z as 3 axes & A is a matrix whose elements corresponds to for each point of x,y,z. How to plot A w.r.t. x,y & z axis?

Attach your data.....

[Manisha Bajaj]

z = 9.5 for all coordinates

x = -3.5:1:4.5

y = 1.5:1:9.5

for Z=9.5

x --> -3.5 -2.5 -1.5 -0.5 0.5 1.5 2.5 3.5 4.5

y

1.5 0.7 0.8 0.7 0.9 0.8 0.8 0.7 0.7 0.8

2.5 0.8 0.8 0.7 0.9 0.7 0.7 0.9 0.8 0.9

3.5 0.8 1 0.9 0.9 0.9 0.9 1 0.8 0.9

4.5 0.7 0.9 0.8 0.9 0.7 0.8 0.8 0.8 0.8

5.5 0.7 0.9 0.6 0.7 0.7 0.9 0.7 0.8 0.9

6.5 0.7 0.8 0.8 0.7 0.8 0.7 0.6 0.6 0.7

7.5 0.7 0.9 0.7 0.7 1 0.6 0.6 0.7 0.8

8.5 0.8 1 0.8 0.8 0.9 0.6 0.7 0.6 0.8

9.5 0.7 0.8 0.8 1 0.8 0.7 0.8 0.8 0.7

Thankyou so much for your response but this doesnt work for my data.. can you share some other idea?

Answer 1

[KSSV]

[X,Y,Z] = peaks(100) ; 
surf(X,Y,Z,Z)

Hi Manisha,

Based on your given data sets (assuming that some large parts of data belong to [A] as shown below from XY). So you have x, y, z vs. A. In this case surf() would be the good option:

XY = [1.5        0.7  0.8  0.7  0.9  0.8  0.8  0.7  0.7  0.8 ;
 
  2.5        0.8  0.8  0.7  0.9  0.7  0.7  0.9  0.8  0.9 ;
 
  3.5        0.8  1  0.9  0.9  0.9  0.9  1  0.8  0.9 ;
 
  4.5        0.7  0.9  0.8  0.9  0.7  0.8  0.8  0.8  0.8; 
 
  5.5        0.7  0.9  0.6  0.7  0.7  0.9  0.7  0.8  0.9 ;
 
  6.5        0.7  0.8  0.8  0.7  0.8  0.7  0.6  0.6  0.7 ;
 
  7.5        0.7  0.9  0.7  0.7  1  0.6  0.6  0.7  0.8 ;
 
  8.5        0.8  1  0.8  0.8  0.9  0.6  0.7  0.6  0.8 ;
 
  9.5        0.7  0.8  0.8  1  0.8  0.7  0.8  0.8  0.7 ];
X =[-3.5  -2.5  -1.5  -0.5  0.5  1.5  2.5  3.5  4.5 ];
Y = XY(:, 1)';  % or Y =1.5:1:9.5;
for ii = 1:numel(X)
    x(ii,:)=[X];
    y(ii,:) =[Y];
end

z = 9.5*ones(9,9);
A = XY(:, 2:end); % 1st column is Y and the rest [A], right?
surf(x, y, z, A), axis tight; shg

Good luck.
