Combining several sets of data in an array into one numeric array to make a histogram

I got 1826 set of data inside variable named X, each set of data inside has several numbers as data. I once use the variable to try making a histogram, but command window says only numeric array can achieve that. How can I transform all data into 1 numeric array and get the histogram. Thanks.

Use vertcat to get the data into a column vector and then use histogram -

%Sample data
X = {rand(22,1); (1:22).'; primes(75).'}

X = 3×1 cell array
    {22×1 double}
    {22×1 double}
    {21×1 double}

Y = vertcat(X{:})

Y = 65×1

0.1986 0.8357 0.4858 0.7844 0.3912 0.9759 0.7271 0.3676 0.2251 0.4418

%Direct call to histogram(), specify the bins as required
histogram(Y)
