Matlab: In for loop, change name of variable

Hi!
I have a variable (vector of size 101x1) in a for loop, named input_reec_PGC1. It is imported from the input_consigne_egal_mesure; on the second line of my code (below).
I define another variable (also vector 101x1), named new_input. Now, I would like to write input_reec_PGC1 = new_input.
My code below works, however, I would like for the input_reec_PGC1 to be programatically generated, from the variable nom_parametre_variant (4th line of code), as I did for the variable variation_du_parametre (5th line of code).
Indeed, I need to do a large number of simulations and the less I need to change my code the better, so I would like the user only to have to write down the nom_parametre_variant and from there the code does the rest.
I tried
eval(['input_', nom_parametre_variant ]) = new_input;
but get the error:
In an assignment A(I) = B, the number of elements in B and I must be the same.
I have the following code:
clear;
input_consigne_egal_mesure;
variation_parametres;
nom_parametre_variant = 'reec_PGC1';
variation_du_parametre = eval(['var_',nom_parametre_variant]);
name_output_file = [nom_parametre_variant, '.csv'];
name_output_folder = char(['results_',nom_parametre_variant]);
if ~exist(name_output_folder, 'dir')
mkdir(name_output_folder)
end
% pwd: current path
path_to_results_folder = [pwd,'/',name_output_folder];
path_to_output_file = fullfile(path_to_results_folder, name_output_file);
solutions = zeros(1000,length(var_VGO)*4);
colonne = 1;
for i = 1 : numel(variation_du_parametre);
% On change le parametre variant
disp(['Variation: ',num2str(variation_du_parametre(i))]);
%% ISSUE HERE
% new_input = variation_du_parametre(i) * ones(1, length(t));
input_reec_PGC1 = variation_du_parametre(i) * ones(1, length(t));
input_reec_PGC1 = new_input;
%%
options = simset('SrcWorkspace','current') ;
sim('mon_modele_INES.slx',temps_simulation, options);
solutions(:, colonne:1:colonne+3)=yout;
colonne = colonne + 5;
end
Thank you in advance for your help!

This is a very bad idea. The severe problems caused by the dynamic creation of variables have been discussed in the forum exhaustively. See: TUTORIAL: Eval
