How can I repeat the following text 5000 times and save the solutions for the 5000 different betas in a 1x 5000 matrix ?

Hello, I make some wild bootstrap here and I now want to repeat the following text(formulas)as a whole 5000 times and save the different resulting beta values in a matrix:
% Estimate the p-values by bootstrapping the residuals.
% resample the residuals with replacement in pairs
% create a Random Variable which follows the Rademacher distribution
rd = ((rand(1,743)<.5)*2 - 1)';
% multiply the res with a random variable of rd Rademacher distribution
% Time Series of Predictors x(t)and r(t)
% computing unconditional mean a2/(1-b), a2=b(1), b=b(2)and build
% time series x(t)* = x2
x2=b(1)+ b(2)*(b(1)/(1-b(2)))+resrd2;
% build time series for r(t)*=rt
% make regressions with the before constructed x2 and rt
% getting with OLS ß*=beta
x3=[ones(size(rt)),x2]; % to have an intercept in the regression
How can I make this in matlab. Thanks for help.

betas = zeros(1, 5000); % make array to store results
for k = 1:5000
% ... your code ...
betas(k) = beta; % store current value in k'th element
