If you have version R2014b or later, you can use the command, and specify the 'Normalization' property to be 'probability':
rng default
x = randn(1000,1);
h = histogram(x,'Normalization','probability');
h.Values will give you the density.

Did you look in the documentation for histogram and see the normlization option:
'Normalization' โ Type of normalization
'count' (default) | 'probability' | 'countdensity' | 'pdf' | 'cumcount' | 'cdf'

Calculating the probability of a data point in a histogram - MATLAB Answers - MATLAB Central
May 7, 2018 - The image below is a histogram of a large data set (90*1 double in blue) and a single data point (in red). I would like to compute the probability of the data (in red) against the blue data points. I could counts the counts on the left of the red bar and divide it by the total counts (90). But I want a matlab code that will do it more efficiently and in a faster way probably without even using the histogram.

March 22, 2018 - So if you imagine the histogram as a X, Y plot, the quantile is fed an Y value and it gives the associated X, I need something that I can feed an X value, and gives me the Y (which is the probability in the histogram). I hope my explanation makes sense. ... https://www.mathworks.com/matlabcentral/answers/390039-how-to-get-the-probability-value-y-for-a-given-x-from-a-probability-normalised-histogram#comment_548446

August 2, 2020 - If your dataset is continuos, than it doesn't make sense to say "how likely is the median", but rather "how likely is an interval around the median" or even to estimate the probability density function of it. Histogram methods are very unreliable for this, so I would advise to use something like ksdensity on your data. ... https://www.mathworks.com/matlabcentral/answers/574006-finding-the-probability-of-a-given-x-value-on-a-histogram#comment_960454
