Matrix multiply with a function
显示 更早的评论
i have two matrix with same columns and rows(matrix a and b). a is depth and b is land use index. each index value has a different equation and it is function of depth. i need to create a third matrix by substituting depth value to the functions.
depth d={2 3 4;7 2 5;1 2 5}
land use l={a b c;b c a;c b a}
a=0.5*depth+3
b=0.78*depth+4
c=0.1*depth+8
I really appreciate your cooperation. Thank you

Sorry the question is not clear to me?
land use l={a b c;b c a;c b a}
Is this cell array with strings? Use??

i = [1:3;2,3,1;3:-1:1];
k = [.5;.78;.1];
f = [3;4;8];
d=[2 3 4;7 2 5;1 2 5];
l = k(i).*d + f(i);
or
l = kron(k(i),d) + kron(ones(size(i)),f(i));

Then you need to load them as variables. I'm sure Google will be able to supply you with dozens if not hundreds of examples of how to read data from Excel to Matlab.
