How to create a matrix?

Hello everyon,

I want to creat a latitude and longitude matrix (180 X 360). The interval is given below:

longitude = 0.25:1:359.75;

latitude = -89.75:1:89.75;

Thanks in advance

Do you mean this?

[lat,long]=ndgrid(-89.75:89.75,0.25:359.75);

@Matt J thanks for your answer.

[lat,long]=ndgrid(-89.75:89.75,0.25:359.75);

this gives individual latitude longitude matrix. I want single matrix (180X360) showing both latititude and longitude.

for example; I want to find a location (Latitude 28.679079 and longitude 77.069710) in 180X360 matrix. Then how would I find the given location?

How about

[lat,long]=ndgrid(-89.75:89.75,0.25:359.75);

matrix=cat(3,lat,long);

so that now, matrix(i,j,:) gives a lat/long pair?

It is not giving desired output
