Remove fields from structure
Syntax
Description
s = rmfield([s](#btt32r0-s),[field](#btt32r0-field)) removes the specified field or fields from structure array s. Specify multiple fields using a cell array of character vectors or a string array. The dimensions of s remain the same.
Examples
Define a scalar structure with fields named a, b, and c.
s.a = 1; s.b = 2; s.c = 3;
Remove field b.
field = 'b'; s = rmfield(s,field)
s = struct with fields: a: 1 c: 3
Define a scalar structure with fields first, second, third, and fourth.
S.first = 1; S.second = 2; S.third = 3; S.fourth = 4;
Remove fields first and fourth.
fields = {'first','fourth'}; S = rmfield(S,fields)
S = struct with fields: second: 2 third: 3
Input Arguments
Input structure, specified as a structure array.
Data Types: struct
Field name or names, specified as a character array, cell array of character vectors, or string array.
Example: 'f1'
Example: {'f1';'f2'}
Data Types: char | cell | string
