Matrix operator error in matlab2019a
显示 更早的评论
Please, can someone help to check what maybe wrong with this code, though it is a part of the entire script
dt=1; % Time step
nHours=numel(LD);
Time=(1:nHours)';
idxHr2Toend=2:nHours;
(NOMb*SOCb(idxHr2Toend-1,:))-Et(idxHr2Toend,:)+(echb*Pbch(idxHr2Toend,:)*dt)-((Pbdch(idxHr2Toend,:)*dt)/edchb)==0;
This the error that keep showing:
Error using optim.internal.problemdef.MatrixOperator
Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in
the second matrix. To perform elementwise multiplication, use '.*'.
Error in optim.internal.problemdef.Mtimes
Error in *
Error in mescode2019 (line 201)
mesprob.Constraints.Batstoredele=(NOMb*SOCb(idxHr2Toend-1,:))-Et(idxHr2Toend,:)+(echb*Pbch(idxHr2Toend,:)*dt)-((Pbdch(idxHr2Toend,:)*dt)/edchb)==0;
Thanks

As it said, have you tried this one?:
To perform elementwise multiplication, use '.*'.
Imagine that you want to multiply/devide the elements of two matrix (element wise)
A.*B
A./B
would work for you.

What are size() of NOMb, idxHr2ToEnd, echb, dt, SOCb ?

As it says again...
24-by-1 and 23-by-1 must agree.
There are vectors with 24 and 23 dimensions.
You should match the numbers either 24 or 23.
