Subscript & superscript equation

cannot manage to add the equation in the mention capture shoot image at the matlab !!!

Tried to use the same sequence mention in https://www.mathworks.com/help/symbolic/add-suffixes-to-symbolic-results.html

but didn't work !!!

Tried latex and it gives another answer than it should become.

Kindly need an assistance in that concern !!!

Answer 1

[Cris LaPierre]

You need to use latex in the equation editor, not symbolic.

This expression x1=x_{b_1}^{a_1} turns into this:

Note that MATLAB only supports a subset of the latex libraries. If you need help building your equation, you can do so interactively in a live script using the equation editor.

the brackets was the problem, haven't used it ........... thank you cris

I think it should be written like that :-

\parallel\upsilon^c_n\parallel={\parallel{P^c_{n+1}-P^c_n}\parallel /\Delta} \leqslant\upsilon_{max}

[Cris LaPierre]

You can also use \frac if you want. This:

\parallel\upsilon^c_n\parallel=\frac{\parallel{P^c_{n+1}-P^c_n}\parallel /}{\Delta} \leq \upsilon_{max}

becomes this:

The Equation Editor creates the expression using slighly different syntax:

\left\|\upsilon_n^c \right\|=\frac{\left\|P_{n+1}^c -P_n^c \right\|}{\Delta }\le \upsilon_{\max}

Once created, you can rt-click on your equation and select 'Copy as latex" if you need to insert the equation elsewhere.

thank you Cris LaPierre .... appreciate your concern

Answer 2

[Mohamed EL-Baz]

the second formula

E_{O,k,n}^d(L_{k,n}^d,P_n^c)={\frac{{N_oB\frac{\Delta}{K}}}{g_{k,n}{(P_n^c)}}\times{(2^{\frac{L_{k,n}^d}{B\frac{\Delta}{K}} -{1})

is that right /?

[Cris LaPierre]

Try it out and see if it displays correctly. As a hint, you can enclose it in dollar signs to turn it into an equation here in the editor.

$E_{O,k,n}^d(L_{k,n}^d,P_n^c)={\frac{{N_oB\frac{\Delta}{K}}}{g_{k,n}{(P_n^c)}}\times{(2^{\frac{L_{k,n}^d}{B\frac{\Delta}{K}} -{1})$

becomes

[Mohamed EL-Baz]

the last number (-1) is subtract from the power not from number 2 !!!!

Answer 3

[Mohamed EL-Baz]

$E_{O,k,n}^d(L_{k,n}^d,P_n^c)={\frac{{N_oB\frac{\Delta}{K}}}{g_{k,n}{(P_n^c)}} (2^{\frac{L_{k,n}^d}{B\frac{\Delta}{K}}} -1)$

I got it

it was a missing bracket in wrong place ........

Thank you Cris LaPierre

[Cris LaPierre]

That works, though with some tweaks you can get it to look better.

$E_{O,k,n}^d \left(L_{k,n}^d ,P_n^c \right)=\frac{N_0 B\Delta /K}{g_{k,n} \left(P_n^c \right)}\left(2\frac{L_{k,n}^d }{B\Delta /K}-1\right)$

S = "m\frac{\partial^2}{\partial t^2}=mg - ky";

symstr = ["'The equation of motion is'"; S;"'where k is the elastic coefficient.'"];

displayFormula(symstr)

doesnot display like that

The equation of motion is

where k is the elastic coefficient.

I dont know why!?

[Cris LaPierre]

In your ded.jpg image, you were trying to use the Edit Equation tool to create your equations, so that is how I've shown you how to create equations.

In your latest question, it doesn't work because displayFormula is for displaying symbolic equations, not latex equations. Follow this example from the displayFormulat documentation page.

S = "m*diff(y,t,t) == m*g-k*y";

symstr = ["'The equation of motion is'"; S;"'where k is the elastic coefficient.'"];
displayFormula(symstr)

The equation of motion is

where k is the elastic coefficient.
