contourm(). (This requires the mapping toolbox)

iam unable to change latitude and longitude values. How to change the already set latitude and longitude in worldmap function

[Walter Roberson]

worldmap(latlim, lonlim)

[Rizwana]

Then how to plot contours of Z in this plot using again worldmap function... Please show me a demo example.

x = 1*264;

y =264*1;

z =264*264;

need a frame like above. x becomes my latitude. Y longitude

Z is my data whose contours are to be plotted.

I don't know. I would need to examine the map axes created by worldmap(), but I do not have that toolbox. Or I would need to do a bunch more reading of the documentation to figure out how the mapping toolbox works internally, which is not easy to do without the software to test with.

I suggest you have a look at the Answer I just gave to one of your other Questions.
