PolarAngle2 = [0:(1/180*pi):pi];

y = y';
SecondNormalizedIntensity = zeros(size(NormalizedIntensity));
for i = 1 : 1: 181

RadiantIntensity = zeros(size(SecondNormalizedIntensity));
RadiantIntensity = RadiantIntensity';
first = integral(polarfun,0,pi);

I would like to ask is there anything wrong with my integral function code?
PolarAngle = [0:(1/60*pi):2*pi]; %incremental of polar angle of sun rays
y = sin(PolarAngle);
y = y';
SecondNormalizedIntensity = zeros(size(NormalizedIntensity));
RadiantIntensity = zeros(size(SecondNormalizedIntensity));
RadiantIntensity = RadiantIntensity';
for i = 1 : 1: 181
SecondNormalizedIntensity(i) = NormalizedIntensity(i) * y(i);
polarfun = @(PolarAngle) (1/SecondNormalizedIntensity);
RadiantIntensity(i) = integral(polarfun{i},-pi/2,pi/2);
end
I met with some errors
Labelled as
Cell contents reference from a non-cell array object.
Error in ShortCircuitCurrentIncrease (line 91)
RadiantIntensity(i) = integral(polarfun{i},-pi/2,pi/2);

polarfun = @(PolarAngle) (1/SecondNormalizedIntensity);
defines polarfun as a single function handle.
RadiantIntensity(i) = integral(polarfun{i},-pi/2,pi/2);
refers to polarfun as if it were a cell array of function handles. The {i} part should not be there.
