Uwe, thank you very much for your comments about my reply to Luca. In my case I have finished a book about trigonometry with 386 pages and obviously there are a lot of formulas and his deduction. All my problem with the method that I sended is reduced to copy and paste for the tables and matrices with too much rows. Respect to your second kindly comment, in the Spanish Navy Naval Military School (I am Commander in the Spanish Navy, Hydrographer) the brackets are omited in the notation to the half addition or difference of trigonometrical functions because the formula, sin1/2(A+B) in purity is the product of sin1/2 (I suppose in radians) and the addition of the angles A and B (also in radians). But in astronomical navigation this has no sense when we use, normally, the Delambre Analogies for the position triangle calculus, so we omit the brackets.

Uwe is right: mathematicians all agree on the typographical rules for typesetting and writing mathematics so there will be no ambiguity in communicating. But when the communication takes place within a closed world, like our navel military formula, I suppose that world can get away with having its own rules, for brevity say. Bruce

### Re: Vertical spacing of matrices

Uwe thank you any other time for your comments, but I think you are wrong about the strict rules to typeset formulas, at least in the trigonometric formulas. For example when you say, (when the sin would not be upright, it would even mean s*i*n*1/2) you don't remember the lineal functions (archs) in a circle that are typed with the first letter upright, like this: Sin AM without brackets; a little more space between Sin and AM is all that it is needed. The trigonometrical functions are the lineal functions in a circle with the radius equal to the unity of mesaure. Then: Sin AM/R=sin a (R = radius) where a is the angle that subtends the AM arch. And also in this case that suffits the space between Sin and AM/R and sin and a to understand correctly the formula. And more, in the trigonometric formulas the strict notation sin(a) is normally not used but sin a, like sin 2a, sin (A+B) and so on, and I think that there aren't confussion about this. And if you type this formulas in LaTeX math mode an aditional space is added between the function and the argument. If you want to search a little that exists more secondary circular functions (due to spanish mariner Mendoza) not used today named Sin v AM (Seno verso), Cos v AM (Coseno verso), and also Ver AM (Verso of AM) or Cov AM (Coverso of AM) and Sub v AM (Subverso of AM). Without brackets.

### Re: Vertical spacing of matrices

Uwe thank you any other time for your comments, but I think you are wrong about the strict rules to typeset formulas, at least in the trigonometric formulas. For example when you say, (when the sin would not be upright, it would even mean s*i*n*1/2) you don't remember the lineal functions (archs) in a circle that are typed with the first letter upright, like this: Sin AM without brackets; a little more space between Sin and AM is all that it is needed. The trigonometrical functions are the lineal functions in a circle with the radius equal to the unity of mesaure. Then: Sin AM/R=sin a (R = radius) where a is the angle that subtends the AM arch. And also in this case that suffits the space between Sin and AM/R and sin and a to understand correctly the formula. And more, in the trigonometric formulas the strict notation sin(a) is normally not used but sin a, like sin 2a, sin (A+B) and so on, and I think that there aren't confussion about this. And if you type this formulas in LaTeX math mode an aditional space is added between the function and the argument. If you want to search a little that exists more secondary circular functions (due to spanish mariner Mendoza) not used today named Sin v AM (Seno verso), Cos v AM (Coseno verso), and also Ver AM (Verso of AM) or Cov AM (Coverso of AM) and Sub v AM (Subverso of AM). Without brackets.

### Re: Vertical spacing of matrices

Uwe, thank you very much for your comments about my reply to Luca. In my case I have finished a book about trigonometry with 386 pages and obviously there are a lot of formulas and his deduction. All my problem with the method that I sended is reduced to copy and paste for the tables and matrices with too much rows. Respect to your second kindly comment, in the Spanish Navy Naval Military School (I am Commander in the Spanish Navy, Hydrographer) the brackets are omited in the notation to the half addition or difference of trigonometrical functions because the formula, sin1/2(A+B) in purity is the product of sin1/2 (I suppose in radians) and the addition of the angles A and B (also in radians). But in astronomical navigation this has no sense when we use, normally, the Delambre Analogies for the position triangle calculus, so we omit the brackets.

### Vertical spacing of matrices

Hi! I'm writing some matrices where I put inside some quite big terms (dfracs for instance). I noticed that it is frequent that some term is too close, almost overlapping, to the element over it. Is it possible somehow to increase the vertical spacing? Thanks!
