use of comma & semi colon

Please explain the meaning of below command in matlab

A(1, 1:9) = [ 30, 25, 16, 32, 15, 37, 18, 3, 10,]

You're asking a very basic question. 5 minutes with any tutorial would have answered it. We recommend that you go through the free matlab onramp to learn the basics of matlab.

Yes, you are right I'm a beginner to matlab. Thanks for providing matlab onramp link, please share more link if availbale so that I can understand Matlab easily.

Once again thank you.

[Guillaume]

There's also the Getting Started tutorial in matlab's doc but the onramp course is more comprehensive.

could you help me to solve a bar graph problem ?

I've two different arrays

a = [2 4 6 8 10]

b = [1 3 5 7 9]

now I want to plot these two array on a single bar graph where x axis values ranges from 1 to 4(1 2 3 4) and y axis contain two different bar graph side by side in different colour, it means at x axis value 1 I need two bar of values 2 & 1 similarly on at x axis value 2 I need two bar of values 4 & 3, similarly at x axis value 3 I need two bar of values 8 & 7, similarly at x axis value 4 I need two bar of values 10 & 9.

[Guillaume]

Again, this is very basic and the documentation of bar has plenty of examples:

bar([a; b].');  %vertically concatenate the two vector and transpose so they're in columns

That means....in the matrix A in the first row (1) the columns one to 9 are filled with [ 30, 25, 16, 32, 15, 37, 18, 3, 10,].

If you want only single array..can be used:

A =  [  30,  25,  16,  32,  15,  37,  18,   3,  10] ;
