Cell array and matrix operation
显示 更早的评论
Hello, I have a 4*4 cell array that has a 10*10 matrix within each cell like below (let's call it C):
C=
And two 10*10 separate matrices let's say:
A=rand(10,10);
B=rand(10,10);
Using these 3 arguments, I want do an operation like below:
(A*C-B*C)/((C^2)*C*(1+(B/C)^2))^(1.5)
Basically, I want to consider each component of the cell (for example C{1} for the first attempt) and do this operation with the B and C for every 16 components of the cell in a repetitive manner. How can I perform this operation? I would appreciate it if someone could please help me. Thank you.

for ii=1:4
for jj=1:4
ANS{ii,jj} = (A*C{ii,jj}-B*C{ii,jj})/((C{ii,jj}.^2).*C{ii,jj}.*(1+(B./C{ii,jj}).^2)).^(1.5);
end
end

Firt of all, the results depend on your C array data and whether you need to perform the matrix operation (1) or elementwise operation (2) e.g.:
%% (1) Matrix multiplication and division
for ii=1:4
for jj=1:4
ANS{ii,jj} = (A*C{ii,jj}-B*C{ii,jj})/((C{ii,jj}^2)*C{ii,jj}*(1+(B/C{ii,jj})^2))^(1.5);
end
end
vs.
%% (2) ELementwise multiplication and division
for ii=1:4
for jj=1:4
ANS{ii,jj} = (A.*C{ii,jj}-B.*C{ii,jj})/((C{ii,jj}.^2).*C{ii,jj}.*(1+(B./C{ii,jj}).^2)).^(1.5);
end
end
