Insert 3D array into Another 3D Array

Hi. I am trying to insert the contents of one 3D array into another. Both represent logical/binary volumes. So far I have,

Y = yMax-yMin;
X = xMax-xMin;
Z = zMax-zMin;

smallArray = ones(Y,X,Z);
bigArray = zeros(500,400,60);
bigArray(yMin:yMax,xMin:xMax,zMin:zMax) = smallArray;

The values of yMin, yMax, xMin, xMax, zMin, zMax, X, Y and Z are within the range of bigArray. For example, yMin = 10, yMax = 120, etc.

But I receive an error about "Subscripted assignment dimension mismatch".

Any guidance would be great, thanks!

Answer 1

[Adam]

yMax - yMin

will always be 1 smaller than

yMin:yMax

because of the inclusive end points (assuming integers, of course, which we are here since they are indices).

e.g.

10 - 1 = 9

but

1:10

clearly gives an array of length 10.

You probably just need to put some +1's in your X, Y and Z
