MATLAB: How to split an array into smaller unequal-sized arrays dependend on array-column values

array

I have an array of 2 column and about 31,000 rows. One of the two columns depicts a spatial coordinate on a grid the other one a dependent parameter. What I want to do is the following:

I need to split the array into smaller parts defined by the spatial column; let's say the spatial coordinate are ranging from 0 to 500 – I now want arrays that give me the two column values for spatial coordinate 0-10, then 10-20 and so on. This would result in 50 arrays of unequal size that cover a spatial range from 0 to 500.

Thank you

Histcounts can be used to pin the data the way you want.

[~,~,BIN] = histcounts(mainArray(:,1), 0:10:500)
subArray1 = mainArray(bin==1,2);
subArray2 = mainArray(bin==2,2);
.
.
.
subArray50 = main array(bin==50,2)

If you set SubarraySteering to Custom, it means you want to control each element individually, thus you need to provide a weights that matches the number of elements. This is different than the SteeringVector since for a subarray, the steering vector is only computed at subarray level. You can specify the weights for each element using ElementWeights option when calling pattern(), like

fc = 10e9;
c = physconst('lightspeed');
lambda = c/fc;
ele = phased.CosineAntennaElement;
antenna_spacing = lambda/2;
element_per_sub = [2 2];
sub_array = phased.URA('Element', ele, 'ElementSpacing', lambda/2, 'Size', element_per_sub);
num_sub_arrays = [2 4];
array = phased.ReplicatedSubarray('Subarray', sub_array, 'Layout', 'Custom', 'SubarraySteering', 'custom');
sub_pos =[];
sub_norm = [];
for ii = 1:num_sub_arrays(1)
    for jj = 1:num_sub_arrays(2)
        sub_pos(:,end+1) = [mod((ii-1),4)*antenna_spacing*2; mod((jj-1), 80)*2*antenna_spacing; 0];
        sub_norm(:,end+1) = [0;-90];
    end
end
array.SubarrayPosition=sub_pos;
array.SubarrayNormal = sub_norm;
taper = taylorwin(sub_array.Size(1)*num_sub_arrays(1)).*taylorwin(sub_array.Size(2)*num_sub_arrays(2))';
% sub_array.Taper=taper;
ws = [];
for ii =1:num_sub_arrays(1)
    for jj =1:num_sub_arrays(2)
        temp_val = taper(element_per_sub(1)*(ii-1)+1:element_per_sub(1)*(ii), element_per_sub(2)*(jj-1)+1:element_per_sub(2)*(jj));
        ws(:,end+1) = temp_val(:);   
    end
end
sv = phased.SteeringVector('SensorArray', array, 'IncludeElementResponse', true);
step(array, fc, [30;30], c, ws)
pattern(array, fc, 'ElementWeights', ws)
