How to convert a table containing numbers and booleans to a double array?

using table2array I get a string array, but I need an array of numbers where the booleans become 0 or 1 respectivly. double(table2array(arr)) results in NaN for every boolean value

It would be easier for us to suggest a solution if you uploaded a representative sample of your data. You can use the paper clip icon in the INSERT section of the toolbar.

T = load('example.mat').data3
M = [strcmpi(T.var1,'TRUE') T.var2]

Here's one way to do that:
T = table(["FALSE";"TRUE";"FALSE";"FALSE"],[1.1;2.2;3.3;4.4],["TRUE";"TRUE";"FALSE";"TRUE"])
[m,n] = size(T);
M = NaN(m,n);
for ii = 1:n
if isstring(T.(ii))
M(:,ii) = strcmpi(T.(ii),'TRUE');
else
M(:,ii) = T.(ii);
end
end
M

One approach would be to use
mask = varfunc(@isnumeric, T, OutputFormat = "uniform");
Output = zeros(height(T), width(T));
Output(:,mask) = T{:,mask};
Output(:,~mask) = varfunc(@(V)strcmpi(V, "TRUE"), InputVariables = ~mask, OutputFormat = "uniform");
