HOW TO USE GREEK LETTER FOR WRITING (LAMBDA /DELTA ) RATIO AND OTHERS

Respected sir,

Please help me in the following things

a) how i will write (lambda/delta) in y axis and graph legend part in greek lettter

b) how i will write tau_0 hat in y axis ,legend part using greek letter

c)how i will write (tau_0 hat/delta) y axis and graph legend part in greek lettter

Answer 1

[Star Strider]

a) frac{\lambda}{\delta}

b) \hat{\tau_0}

c) \frac{\hat{\tau_0}}{\delta}

Are these what you want?

[Souvick roy]

i want to write in x axis lambda hat/delta hat

i have wriiten xlabel=('$$\hat{\lambda}/\hat{\delta}$$','Interpreter','Latex')

it shows error

Error: File: yieldpointvary.m Line: 7 Column: 41

Expression or statement is incorrect--possibly unbalanced (, {, or [.

[Walter Roberson]

Remove the "="

xlabel('$$\hat{\lambda}/\hat{\delta}$$', 'interpreter', 'latex')

[Souvick roy]

ok. but another error shows for when i am going to write for y_0 and y_0/h

ylabel('$${\y_0}$$','Interpreter','Latex')

ylabel('$${\y_0}/{\h}$$','Interpreter','Latex')

[Walter Roberson]

What are you expecting \y to mean?

If you are expecting \y to be gamma, then use \gamma

[Souvick roy]

y_0 is a location of a point .

gamma=[0.01:0.005:2]
delta=0.02
n=gamma/delta
beta  = 0.1
y0 = -gamma.* log(beta)
plot(n,y0)
xlabel ('$$\hat{\lambda}/\hat{\delta}$$','Interpreter','Latex')
%ylabel('$${\y_0}$$','Interpreter','Latex')
%ylabel('$${\y_0}/{\h}$$','Interpreter','Latex')
ylabel=('y_0/h');

i want level x axis by lmbda hat/delta hat and y axis as y_0 hat or y_0/h where y_0 is a location of a point .

[Walter Roberson]

Your last line there should be

ylabel('$$y_0/h$$', 'Interpreter', 'latex');

[Souvick roy]

still error showing

Index exceeds matrix dimensions.

Error in yieldpointvary (line 11)

ylabel('$$y_0/h$$', 'Interpreter', 'latex ')

[Walter Roberson]

You forgot to "clear ylabel" after you accidentally used "ylabel=" before.

With respect to legends: it is not possible to directly specify the Interpreter property when you call legend(). However, you can assign the result of calling legend() to a variable, and then set the Interpreter property of that handle.
