I display a matrix (n x m) in one of my cards. The method I use is limited. I have described my method in the following paragraphs. I would appreciate any SUGGESTIONS for improving my method and ALTERNATE ways of displaying a matrix. _________________________________________________________________ Displaying a Matrix In one of the cards in my stack, I display a matrix. Since the matrix is very large, I display only a part of the matrix. The way I do this is as follows: I display four columns at a time. Each column is a vertical scrolling field. There is also a horizontal scroll bar. On scrolling horizontally, the displayed values are stored in a global variable, and the columns are updated depending on the direction of scrolling. The columns are updated based on the matrix elements stored in the global variable. On leaving the card, the global variable is again updated. Problem: If I have a n x m matrix, I display 4 rows and 4 columns only. The performance (i.e. horizontal scrolling) in this case is sluggish but acceptable. In case I display 8 rows and 8 columns the horizontal scrolling becomes very slow. Does anyone have any alternative method for doing this i.e. displaying a matrix of numbers? Or any suggestions how I could improve my method? Nilanjan MECEGY@uhvax1.uh.edu
