converting lat,lon column vectors to corresponding grid vector (lon*lat)

Hello

I have lat , lon column vectors

lon=35*1

lat=33*1

Now i want to convert it into single column vector that will have corresponding grid size(1155*1) , i.e 35*33 =1155

lat_lon = lat*lon';
sz = size(lat_lon);
lat_lon = reshape(lat_lon, [sz(1)*sz(2), 1]);
size(lat_lon); %(35*33)x1

This gives you a vector of size (35*33)x1

Actually the above command gives 68*1.

I have 35 lon points , 33lat points. To find the total num of grid points i must mul , 33*35, which gives 1155. But i dont know how to mul column matrix of different size

You can use matrix multiplication to multiply the column vectors and then reshape it to get your desired vector.

lat_lon_non_column = lat * lon';
lat_lon_desired = reshape(lat_lon_non_column, [1155, 1]);
