My data is stored on a single Excel file, where each sheet containts several numeric matrixes. I imported all the variables successfully to MATLAB using readmatrix. However, 1x1 matrices are imported incorrectly. I use the following syntax:
MFOA = readmatrix (Path, 'Sheet', Sheet, 'Range', 'H142:H142');
Instead of loading only the cell H142, readmatrix loads a column vector starting from H142 down to the last row of the rectangular portion of the spreadsheet. How can I get the correct results?

I have the same issue, have you found out any new solution or reasoning?

It's a bug; the workarounds are simple enough, but never hurts to submit additional bug report to prod TMW along in fixing stuff...

Don't have recent-enough version here to test to confirm, but if is so and reproducible on latest release, that would appear to be a bug. Report to TMW.
Workarounds:
  1. Just follow above with MFOA=MFOA(1); to throw away everything but first element, or
  2. Use venerable xlsread to read the single cell cases (I'd use 1. btw).

With what, specifically? If there's only one value, doesn't it work correctly?
