I'm having trouble assigning a string value ('practice') to every level of a structure called unshuff.
These work:
unshuff(1,1).myfield = 'practice';
unshuff(1,2).myfield = 'practice';
But this does not work:
unshuff(1,:).myfield = 'practice';
I get an error message that says:
Insufficient outputs from right hand side to satisfy comma separated list expansion on left hand side. Missing [] are the most likely cause.
How can one (efficiently) assign a string value to every level of a given field in a structure?

Here is one way:
[unshuff(1,:).myfield] = deal( 'new practice' ) ;

You're welcome. Here is another way that you could profile if relevant:
newVals = repmat( {'new practice'}, 1, size( unshuff, 2 )) ;
[unshuff(1,:).myfield] = newVals{:} ;
To understand what we are doing in both cases, you have to understand Comma Separated Lists (CSL) in MATLAB.
