I have matlab data ("vand_sph61-11.mat") which i linked here. this data has spherical cordinates in binary form and has 3-d array. this data has 1801x59x109 size. 1801 is range by getting from dividing 5 meter to 50 meter into 2.5 cm. 59 is transmitter beams by getting from dividing -29 degree to 29 degree into 1 degree. 109 is receiver beams by getting from dividing -54 degree to 54 degree into 1 degree. I want to convert this data into cartesian cordinates which has floating type.
In this data, i created a 3-d object in which when point exist then have binary value '1' otherwise have binary value '0'.
please help me

So you want to find the indices in your 3D array and convert those indices to the values of the three vectors you describe?

%find 3D indices in M
[r,c,p]=findND(M);
%create lookup tables
lookup=struct;
lookup.r=5:.025:50;
lookup.c=-29:29;
lookup.p=-54:54;
%convert indices to physical dimensions
r=lookup.r(r);
c=lookup.c(c);
p=lookup.p(p);

'it is not working' does not provide any useful information. As I said in my comment these two lines of code are not enough to get your desired output. So what code did you try?
