adding a value until a particular value

Hi,

questions never end!

I have an array 17x365 and some initial values in the first row.

So I would like to add a particular number in every column like this: example First element in each row=[1], I an external value (let's say 2).

So I would add the value 0.52 in each time step like this [1 ; 1.52; 2.04; 2.56;3;3;3;.....]

I add the value 2, in small amount of 0.52 until it is depleted and then take the final value (3) and put it in the rest of the column

I don't know if I explained it well

please help!!

thanks>>!

>> stp = 0.52; % step
>> ini = [1,4,2,0]; % initial value
>> mxv = [3,7,4,3]; % max value
>> num = 10; % number of rows

and now generate the matrix:

>> vec = stp*(0:num-1).';
>> mat = bsxfun(@plus,ini,vec);
>> mat = bsxfun(@min,mat,mxv)
mat =
          1            4            2            0
       1.52         4.52         2.52         0.52
       2.04         5.04         3.04         1.04
       2.56         5.56         3.56         1.56
          3         6.08            4         2.08
          3          6.6            4          2.6
          3            7            4            3
          3            7            4            3
          3            7            4            3
          3            7            4            3
