MATLAB: What does Assignment has more non-singleton rhs dimensions than non-singleton subscripts mean

3d matrixerrormatrixnon-singleton error

Hey in a project I am trying to build a 3d matrix based off another 3d matrix to find a final temperature profile. The code up to the error is:
X = 0:0.1:5;
Y = 0:0.1:1;
Z = 0:0.1:20;
layer = zeros(length(X),length(Y));
layer1 = layer;
layers = layer;
layer1(:,:) = 52;
layers(:,:) = 22;
temperature_profile(:,:,1) = layer1;
for x = 2:length(Z)
    temperature_profile(:,:,x) = layers;
end
layers2 = layer;
layers2(:,:) = 1;
for x = 1:length(Z)
    temperature_profile2(:,:,x) = layers2;
end
H = zeros(length(X),length(Y),length(Z));
H(:,:,:) = 0.0000001;
G = ones(length(X),length(Y),length(Z));
V = temperature_profile2-temperature_profile;
t = 0;
Cp = 1;
V = 1;
A = 1;
rho = 1;
h = 1;
T0 = 22;
T1 = 52;
k = 1;
T = V < H;
while T ~= G
    for z = 2:length(Z)
        for y = 1:length(Y)
            for x = 1:length(X)
                if z == 1
                    temperature_profile2(x,y,z) = 52; 
                elseif z == 2
                    if y == 1
                        if x == 1
                            temperature_profile2(x,y,z) = ((0.00001)./(V.*rho.*Cp)).*(V.*k.*((((temperature_profile(x+2,y,z)-temperature_profile(x,y,z))./(0.2^2)))+(((temperature_profile(x,y+2,z)-temperature_profile(x,y,z))./(0.2^2)))+(((temperature_profile(x,y,z+2)-3.*temperature_profile(x,y,z)+2.*temperature_profile(x,y,z-1))./(4.*(0.2^2))))+A.*h.*(T0-T1)))+temperature_profile(x,y,z);
when it is run the Assignment has more non-singleton rhs dimensions than non-singleton subscripts mean error pops up and i'm not really sure what it means.

Figured out the problem V was later replaced with a 3d matrix later in the code on accident, the problem is fixed.
