y(1)=302.6:0.0055:332.3;

y(2)=305.9:0.0096:355.2;

New=(14.58E-4-5.89E-12.*(y(1).^4-8.08E+8)-11.86E-4.*(y(1)-302.8)+18.84E-4.*(y(2)-y(1))^1.27)/(y(2)+y(1)).^0.31+5.37E-12.*(y(2)^4-y(1).^(4));

Ending with the following error

Unable to perform assignment because the indices on the left side are not compatible with the size of the right

side.

Error in Untitled2 (line 2)

y(1)=302.6:0.005:332.3;

I suspect I know a bit of what's going wrong.. yet I'm at a loss for how to fix it.. Any help is much appreciated

You can't do that-

y(1)=302.6:0.0055:332.3;

y(1) refering a y array with index postion 1, how can you save multiple values on single array location?

Same can be allowed if you define cell array y{1}

See example

#Allowed

>> s(2)=5
s =
     0     5

#Not Allowed

>> s(2)=1:1:5
In an assignment  A(:) = B, the number of elements in A and B must be the same

You can try with change the names of array variables as y1 and y2
