MATLAB: Decimal number as filed name of a structure

field name

how can I set this as field name ? since it has a decimal in it , Matlab doesn't accept it to be field name . If i could get rid of the dot, it works but i don't know how ?

'One_IMj_4_Story_Selected_Records_Set_0.01SA_0.99dNSA'.

You could find and replace the dots ...

fn = 'One_IMj_4_Story_Selected_Records_Set_0.01SA_0.99dNSA'
fn2 = regexprep(fn,'\.','_dot_')
fn2 =
      'One_IMj_4_Story_Selected_Records_Set_0_dot_01SA_0_dot_99dNSA'

MATLAB: Simple operations with struct

idx = [struct_name.fieldname] > 50000;
new_struct = struct_name(idx);

new_struct will only contain elements where the field name is greater than 50000.

If you don't want to delete those elements, and just want to set them to 0,

new_struct = struct_name;
idx = [new_struct.fieldname] > 50000;
[new_struct(idx).fieldname] = deal(0);

In this case, new_struct will have same elements as original struct_name but the elements set to 0.

MATLAB: Want to combine 4 structures into 1

You shouldn't have numbered your variables in the first place. That only leads to problems. Put them together in an array.

If I understood correctly, this should give you more or less what you want:

Allsituations.Human = Human1;
Allsituations.Auto = Auto1;
Allsituations(2).Human = Human2;
Allsituations(2).Auto = Auto2;

Or as a more efficient but slightly more obscure one liner:

Allsituations = struct('Human', {Human1, Human2}, 'Auto', {Auto1, Auto2});
