Creating Array Struct From excel file

I am trying to create an appropriate array from an excel sheet. I have read the sheet with [num str]=xlsread('Book1.xlsx'); This creates Name Size Bytes Class Attributes

num       5x10              400  double       
and 
Name      Size            Bytes  Class    Attributes

str       6x10             6920  cell  
I would like to create a struct such that the field names coming from the row headers of str. but if i try
B=struct(str(1,1),num(:,1))
I get an error
Error using struct
Field names must be strings.

Please suggest a work around if you know of one. Thank you

Your str is a cell string. Then you need curly braces:

B = struct(str{1,1}, num(:,1))

field_name = 'field_to_be';
myStruct.(field_name) = 4;
>> myStruct

myStruct = 

      field_to_be2: 4

[David Sanchez]

Try the above with your cell-names. Do not mind about the "2" in the:

field_to_be2: 4

it's been a mistake will copying from my command window

@David: Instead of explaining, that we should ignore the "2", you can simply edit your question and delete it.

I am not sure if I am following this right...Should I manually name the fields? I do need it to be read off the excel sheet. If you could please explain a bit further, I would appreciate it. Thanks
