how to change the xtick of the picture into 10 power format?

hi

I plotted one graph which is attached herewith. Now I want to change the x-axis ticks into 10 power format. for e.g

xticks=[-30 -25 -20 -15 -10 -5 0 5 10] 
into 

xticks=[10^-30 10^-25 10^-20 10^-15 10^-10 10^-5 10^-0 10^5 10^10]

when I manually change it, it shows '^' or 'E' sign, but I need in power format like 10 power -30. kindly help me I will be highly thankful to you

regards
mudasir

doc XTickLabel

You can set the labels to be whatever you want, using sprintf to format as you choose also.

Dear Sir Adam

I tried a lot to do it using different ways. but unable to do this. can your kind-self give one one favor to me and perform 4 5 line code and paste here. I will be highly thankful to you

[Adam]

prefix = '10^';
xticklabels = cell.empty( 0, numel( xticks ) );

for i = 1:numel( xticks )
   xticklabels{i} = sprintf( '%s%d', prefix, xticks(i) )
end

There may well be a way to do that without the for loop, but I don't have time to work it out if there is and for just setting tick labels speed shouldn't really be an issue anyway so that should work.

Then just set these as the

XTickLabel

property of your axes.

Dear Sir,

I have Matlab R2014a version but following commands are not executed.

xticks
xticklabels

i think they come in after 2014 version.

[Adam]

They are variables, not commands. You can call them anything you want. You named the variable xticks yourself in your question, I just followed that with adding xticklabels.

[Mudasir Ahmed]

Dear Sir

after running the code I get the following results,

xticklabels = 

    Columns 1 through 5

      '10^-30'    '10^-25'    '10^-20'    '10^-15'    '10^-10'

    Columns 6 through 8

      '10^-5'    '10^0'    '10^5'

Now my question is Sir, how to give this data which change and modify the labeling of graph (plot). as shown in attached picture in question.

I tried the following command

https://www.mathworks.com/help/matlab/creating_plots/change-tick-marks-and-tick-labels-of-graph-1.html

xticklabels

but is not supported in Matlab 2014a.

[Adam]

set( hAxes, 'XTickLabels', xticklabels )

should work fine.

I didn't actually realise xticklabels is now a function (introduced in R2016b) so this is not a good name for the variable.

[Mudasir Ahmed]

Thank you so much sir, for your kind help. but it is still not working. after that graph is attached herewith

Dear Sir, i am pasting my code here.

After plot, I need to change x-axis into 10 power format. but here ^ comes. which I don't need. Kindly help me, sir.

[Adam]

You appear to have two axes in the same figure on top of each other there.

Just create 1 axes, keep its handle and explicitly use that handle in plotting and other instructions.

[Mudasir Ahmed]

Bur sir still ^ sign is there. i need -30 in superscript
