How can i convert array 3d array into 3 column(ranked)
INPUT
SPEED=[1 2]'
TRQ=[10 20 30]
Z=[0 1;3 5; 4 3]
A=TRQ
B=SPEED'
STEP1 -Convert Table into Array
STEP2 -Sort Array based on Z
Result=[{'SPEED', 'TRQ','Z'},[2;1;2;1;2;1],[20;30;30;30;10;10],[5;4;3;3;1;0]]

Step0 = [{'', '', 'SPEED', ''};
{'', 'Z'}, num2cell(SPEED.');
{'T'; 'R'; 'Q'}, num2cell(TRQ(:)), num2cell(Z) ];

SPEED=[1 2]'
TRQ=[10 20 30]
Z=[0 1;3 5; 4 3]
[x,y] = ndgrid(TRQ,SPEED);
T = array2table([y(:),x(:),Z(:)],'VariableNames',{'SPEED','TRQ','Z'});
Tout = sortrows(T,{'Z','SPEED'},{'descend','descend'})
without using table
[x,y] = ndgrid(TRQ,SPEED);
T1 = [y(:),x(:),Z(:)];
T2 = sortrows(T,[-3,-1]);
out = [{'SPEED','TRQ','Z'};num2cell(T2)];
