Error Assignment has more non-singleton rhs dimensions than non-singleton subscripts

Hello there, I'm a Matlab newbie. I'm getting this error when running a function

Assignment has more non-singleton rhs dimensions than non-singleton subscripts

Assignment has more non-singleton rhs dimensions than non-singleton subscripts

Error in AQDATABT (line 251)
        mpc.branch(idr,3)=(Rphase(ind)*LUNG(i))/1000;

and I can't understand where's the error.

Rphase(ind) is 1.9 and LUNG(i) is 9.

Thanks for help

What is "idr"?

Put a breakpoint on the line in question in the code (or use the stop on error option) and type the following on the command line to see what size the two sides of the assignment are. They need to be the same size (or at least any differences must just be of the form of extra singleton dimensions - i.e. '1' in the size output) for the assignment to make sense.

size( mpc.branch(idr,3) )
size( Rphase(ind)*LUNG(i) )

Type:

doc dbstop

if you want top know about adding breakpoint options programatically. Personally I just use the options in the editor 'Breakpoints -> Stop on errors' to stop only when there is an error or just click on the margin next to the line number to add a specific breakpoint, but a lot of people seem to use the dbstop approach instead).

size( mpc.branch(idr,3) )

returs 1 1

size( Rphase(ind)*LUNG(i) )

instead 2 1

This is pretty strange because Rphase is a 246x1 array and LUNG is a 50x1 array.

Solved! ind is actually 2x1
