Currently, the RegionFile (line 52) class extends the file if it's size is not a multiple of 4KB, but does it in a inefficient way:
for(int i = 0; i < (this.file.length() & 0xfff); i++) {
this.file.write(0);
}That code could potentially cause up to 4095 file extensions, when we could just do them at once with the following code:
| clear; | |
| T = 7; | |
| f = @(x, y) exp(-T * (x.^2 - y.^2)) - exp(-T * (x.^2 + y.^2)); | |
| xa = 0; | |
| xb = 2; | |
| ya = 0; | |
| yb = 3; | |
| S = adapsimpson2(f, xa, xb, ya, yb, 1.e18) |

| # Based on https://github.com/jekyll/jekyll/blob/master/lib/jekyll/tags/include.rb, | |
| # provides a transclude block that maintains Jekyll include semantics. Files can | |
| # pass parameters to transcludes via the `include` object, with the addition of | |
| # {{ include.content }} which includes the block content. | |
| # | |
| # Transcludes must be located in Jekyll's _includes dir. | |
