I am designing a code to find the cheapest gear box pair that can meet a certain force requirement.
The requirement, for example in my code is WearPinionLD, is a 37x7 matrix, and Ft the force is 37x1 matrix. I intend to find the indices of the WearPinionLD of each row w.r.t the same row of Ft with for loop:
for i=1:37
index(i)=find(WearPinionLD(i,:)>=Ft(i));
end
but matlab said the LHS and RHS sized differently.

Ran in:
WearPinionLD = rand(37,7);
Ft = rand(37,1);
for i=1:37
index{i} =find(WearPinionLD(i,:)>=Ft(i));
end
index.'
ans = 37×1 cell array
{[ 1 2 3 4 6 7]} {1×0 double } {[ 2 5 6 7]} {[ 6 7]} {[ 1 4 5 6 7]} {[1 2 3 4 5 6 7]} {1×0 double } {[ 2 3 4 6 7]} {[ 2 3 4 5 6 7]} {[ 2 3 4 7]} {[ 1 2 5 6 7]} {[ 1 4 6 7]} {[ 1 2 3 4 5 6]} {[ 3 4]} {[ 3 6]} {[ 1 3 4 5 6 7]}

As the indices array are irregularly sized based on find condition, use a cell array.
