5D Data with scatter3?

It seems like you should be able to plot 5D data with scatter3 using the three coordinates, the marker size, and the color. I can't figure it out, though. Here's my equation:
I had it working fine while fixing one variable and using meshgrid for the calculation and color to represent the LHS, but can't figure out how to include all five variables. Since meshgrid only goes up to three dimensions, I'm not sure that's a viable way. I thought there might be a simple "trick" by just repeating the calculation and using hold on with the plot, but I haven't gotten that to work either. I tried something akin to:
for variable1
for variable2
for variable3
for variable4
scatter3(variable1,variable2,variable3,variable4,LHS), hold on
This only returns a plot of data along a corner-to-corner diagonal. What's the right way to plot with all five variables?

All the data are created within the script, so I can make them whatever I want.

It is possible to plot with five arrays:
[x, y, z] = peaks;
s = 10*(x.^2 + y.^2 + 1);
c = abs(z);
scatter3(x(:), y(:), z(:), s(:), c(:))
Perhaps if you show us a sample of code we can execute and describe how the behavior of that code differs from how you want it to behave we may be able to offer more targeted suggestions for how to achive your goal.

Oof. I had this at one point, but I was plotting with a combination of number of points and marker size that made it look like a filled contour instead of individual points, so I thought it wasn't working!
