Hi,
you can obtain your plot by using 'bar' matlab function (reference: https://www.mathworks.com/help/matlab/ref/bar.html).
For example if you run the following lines:
x = -1.5:0.1:1.5;
y = zeros(1,31);
y(10) = 0.8;
y(15) = 0.6;
bar(x,y,0)
you obtain the following plot:
The 3rd input argument of bar function specify the width of each bar. In this case it is set to 0 in order to obtain your plot.
Then you can control label of x-axis and y-axis by using xlabel and ylabel function (example: xlabel('Coefficient value'), ylabel('Distribution') and set axes limits by using xlim, ylim functions.
