Getting data from a struct array using dynamic field references

I have a struct that looks like this:

data = 

      GS_L: {411x9 cell}
      GS_R: {27x9 cell}
      GS_U: {27x9 cell}
      GS_D: {27x9 cell}

and a cell that looks like this:

OECFMES = 

      'GS_L'
      'GS_R'
      'GS_U'
      'GS_D'

But when I try to acces data from the struct I get this error message.

>> data.(OECFMES(1))
Argument to dynamic structure reference must evaluate to a valid field name.

When I type it manually like this:

data.('GS_L')

It does work however

What am I doing wrong?

Kind regards,

The difference is simple:

• () parentheses refer to the cells themselves.
• {} curly braces refer to the cell contents.

You can read more about indexing cell arrays in the documentation.

Replace

    data.(OECFMES(1))

by

    data.(OECFMES{1})
