setcellstruct

SETCELLSTRUCT sets the field values of MATLAB cell array of structures

   Note that the calling syntax must be in the form of assignment:
   CELLARRAY = SETCELLSTRUCT(CELLARRAY,...)
   MATLAB does not modify variables that only appear on the right
   hand side as arguments.

 Numeric data
 ---------------------------------------------------------
 CELLARRAY = SETCELLSTRUCT(CELLARRAY,'field',INDEX,VALUE,M,N)
     Sets (M,N) element equal to VALUE when the field data is
   a matrix. The assigned VALUE may be
   1. Scalar numeric value to be written to all CELLARRAY elements
   2. Numeric array of the same length as INDEX array

 CELLARRAY = SETCELLSTRUCT(CELLARRAY,'field',INDEX,VALUE,M) can be used
   for one dimensional vectors

 CELLARRAY = SETCELLSTRUCT(CELLARRAY,'field',INDEX,VALUE) is the same as
   SETCELLSTRUCT(CELLARRAY,'field',index,1,1) if the field data
   is a scalar

 Character array
 --------------------------------------------------------------------
 CELLARRAY SETCELLSTRUCT(CELLARRAY,'field',INDEX,VALUE) is a MATLAB
   cell array of strings when specified fields contain strings.
   The assignment VALUE may be
   1. Character string, 
   2. Character array with the number of rows matching the number of
       elements in INDEX array,
   3. Cell array of strings, with either one element or with the same
       length as index.
