Plotting 4D surface plot (x,y,z and one is colour bar)

I have some output from a complex relation , the 4 variable are in coloumns as x,y,z, and m and I need a 4D data surface plot,( not using scatter3 ) the data are as given below

hello

what have you tried so far ?

[Sanjib]

I tried scatter3 and plot colour bar, but can not plot surface plot ,kindly please help me plotting the surface plot.

scatter3(A(:,1), A(:,2), A(:,3),[], A(:,4),'filled')
colorbar

[Sanjib]

Thank you sir, but I need surface plot instead of scatter plot.

[KSSV]

For the data give, surf cannot be plotted.

[Sanjib]

Actually I need continues relationship among them instead of scattered relationship

[Sanjib]

I can plot the surface plot for x,y,z but can not introduce m, the 4th variable as colour bar; please check the code
