Structures are a convenient way of carrying around many variables as a single object and of passing those variables to a function packed in a single argument.Once a structure has been passed to a function, however, many users (according to various Newsgroup posts) find it tiresome to have to access its fields repeatedly through dot-indexing notation and have sought automated ways to take a structure and assign all of its fields to separate variables, as ina = myStruct.a;b = myStruct.b;c = myStruct.c;etc...Solutions based on assignin() have often been tried, but are hazardous, for reasons discussed, for example, in this thread:http://www.mathworks.com/matlabcentral/newsreader/view_thread/244639#628695The structvars() tool in this FEX submission does something virtually as good and far safer.Given a structure, it will print a set of assignment commands that, if executed, would assign fields of a structure to individual variables of the same name (or vice versa). The expression produced by structvars() can be conveniently copy/pasted from the command window to the file editor at the location in the file where the variables need to be unpacked. Examples: Given structure myStruct, with fields a,b,c, & d (1) structvars(myStruct) %assign fields to variables ans = a = myStruct.a; b = myStruct.b; c = myStruct.c; d = myStruct.d; (2) structvars(3,myStruct) %split the last result across 3 columns ans = a = myStruct.a; c = myStruct.c; d = myStruct.d; b = myStruct.b; (3) structvars(3,myStruct,0) %assign variables to fields ans = myStruct.a = a; myStruct.c = c; myStruct.d = d; myStruct.b = b; The commands can obviously be regenerated if you add/remove structure fields later on. On the other hand, the effort of just making these incremental edits manually is typically minimal.
