I have a mx1 cell in A table as Scenario column. I want to find the index matching the string 'Scenario #' using following:
Scenario_list=A.Scenario(Scenario==['Scenario 20']);
Received a "Error using == Matrix dimensions must agree." error message.

For comparing a cell array of char vectors and a char vector you have to use strcmp, or strcmpi, or strncmp, etc:
idx = strcmp(A.Scenario,'Scenario 20')
The == operator only works for string arrays:

Do not confuse character vectors or character arrays with string arrays:

Replace
Scenario==['Scenario 20']
with
strcmp(Scenario,'Scenario 20')
If you'd like to ignore case, use strcmpi().
