Since I cannot know how many rows I will need, I tried to add rows dynamically, but I didn't find any function in the Origin help. My matrix are global variables. I wrote a function which redifined the matrix, with greater number of rows. (with eventually a temporary matrix to store the data of the main matrix to copy it in the first row of the new extended matrix.) But since i do those operations in a function, it seems that the range of the extended matrix is limited to this function. So, finally, my matrix is still too small. Then I thought that I could give my function the adress of the matrix, in order to avoid the problem of the range, but i didn't find how to free the memory occupied by the smaller instantation of my matrix. Am I on the right way ? Otherwise, how could I bypass this problem please ? Thanks, Simon Nicolas.
