Symbolic toolbox expressions in table() not shown as LaTeX in livescrit.

The title says it all.

Symbolic ToolBox expresions are shown as latex, but is I use table to format my output, as in

table(symbol_column_vector,corresponding_duble_columvector)

expresions are shown in plain text.

Thanks

Thanks Walter.

This is a very nice trick!!!

I think we've hit a bug. This code mis behaves (becouse the combination with symbolic expressions), giving an unreal big number of low significant decimals:

syms a b c d real
[[a,a+b,c-d]', vpa([1,2,3.1234]',3)]

While

syms a b c d real
[[a,a+b,c-d]', vpa(round([1,2,3.1234]',3))]

runs just OK.

Thanks a lot!!!.

The trick is not to be working always.

So the bug seems defficult to be worked arround

vpa(-1.3159473)

Is not working as expected

[Walter Roberson]

syms a b c d real
disp([[a,a+b,c-d]', vpa(round([1,2,3.1234]',3))])

Thanks Walter,

But still, vpa is not working as expected in a variety of cases .

Using vpa with a matrix of string-s representing the number or char arguments seems to work in every case

syms a b c d real
[[a,a+b,c-d]',vpa(string(round([1,2,3.1234]',3)))]

This behavior of vpa, the need to use such a trick, seems like a bug to me.

Thanks again!.

Correct. table() is not designed for fancy display formatting.

[Javier Ros]

Yes.

But an altenative should be in place, as long as Live Editor is intended for that. Shouldn't it?

[Walter Roberson]

Just do

[symbol_column_vector, vpa(corresponding_double_columnvector,NUMBER_OF_DECIMAL_POINTS)]

This will create a symbolic array with columns aligned. It will be displayed with ( ) around it, though.
