matlab struct initialization issue
显示 更早的评论
I'm trying to initialize a strut which would have fields that represent age groups like <39, 40-49, 50-59 and so on. So I tried the following
x = struct('below39',{},'AG 40 to 49',{}); but it gives me an invalied field name error. I also tried
x = struct('below39',{}); and that worked. I'm not sure why is this an issue. Any insights would eb helpful.

In MATLAB, the struct fieldnames cannot have spaces. The following will work
x = struct('below39',{},'AG_40_to_49',{})
Read here about rules to for creating a fieldname: https://www.mathworks.com/help/matlab/ref/struct.html#d122e1258552

See matlab.lang.makeValidName and isvarname()

@Anmol Pardeshi, yes. The link mentions the rules to define a fieldname.
@Per Isakson, Thanks for the information.
