Hi all; I've written a program including some cells like below:
clc; clear;
s=[ 0 10 20 30];
pr=[0.24 0.40 0.36];
f=[625 425 425; 125 125 125; 25 25 25; 125 125 125];
sm=[30 20 10 0;-10 30 20 10;-10 -10 30 20];
for n=1:10
fmin_init{n}=f;
for t=1:3
for ss=1:4
s2{t,ss}= sm,
for qq=1:3
tsd_intrpln{n,qq}=interp1(s(:),fmin_init{n}(:,qq), s2{t,ss});
end
% my problem is here >> tsd{n,ss}= Pr.* tsd_intrpln{n,:}
end
end
end
I want to multiply each element of matrix "pr" i.e. [0.24 0.40 0.36] respectively by each element of matrix "tsd_intrpln{n,1}" and its equevalant element in "tsd_intrpln{n,2}" and also "tsd_intrpln{n,3}" for example:
-the first element of "tsd_intrpln{n,1}" is multiplied by "pr(1) " . i.e. a11* 0.24
-the first element of "tsd_intrpln{n,2}" is multiplied by "pr(2) " . i.e. a'11* 0.4
-the first element of "tsd_intrpln{n,3}" is multiplied by "pr(3) " . i.e. a''11* 0.36 .
How can I do this. I look forward to reply.m

I seem to give a lot of answers that use arrayfun, and I don't want to be cliché, but it seems you need it here to pull out the element from each matrix.
tsd{n,ss} = pr .* arrayfun(@(x) tsd_intrpln{n,x}(1,1), 1:3);
