Error in inline expression ==> Not enough input arguments.

I hav attached my code below. When i try to run the inline command it always says error in inline expression.

Basically, I'm trying to use cells to process a large amount of data from an FEM software.

Initially, i try to create a stress tensor and then the hydrostatic part and deviatoric part, which are basically matrices.

hypsph is a function consisting of two variables which is also shown below.

S{41976}=zeros(3,3,39);

for col=1:41976

for row=1:39

S{col}(:,:,row) = [S11(row,col), S12(row,col), S13(row,col)

S12(row,col), S22(row,col), S23(row,col)

S13(row,col), S23(row,col), S33(row,col)];

end

end

%% 3. Creating Hydrostatic stress and Deviatoric Stress Tensor

SD{41976}= zeros(3,3,39);

SH{41976}= zeros(1,39);I=eye(3,3);

for col=1:41976

for row=1:39

SH{col}(:,row)=(S{col}(1,1,row)+S{col}(2,2,row)+S{col}(3,3,row))/3;

SD{col}(:,:,row)= S{col}(:,:,row) - (I)*SH{col}(:,row);

Svec{col}(:,:)= [(sqrt(3)/(2*SD{col}(1,1,row)))

SD{col}(2,2,row)-SD{col}(3,3,row)

SD{col}(1,2,row)

SD{col}(1,3,row)

SD{col}(2,3,row)]';

% Svec{col}(1,1,row)=0;

end

end

%% plot

clc

a(:,:)=Svec{2};

J2m_iniz = (max(a) + min(a)) ./2;

f=inline('hypsph','Sp','S');

[J2m,J2ai,J2a] = fminimax(f,J2m_iniz,[],[],[],[],[],[],[],options,a);

%%%%%%%%%% hypsph function

function z = hypsph(radqJ2m,sv)

x1 = radqJ2m(1);

x2 = radqJ2m(2);

x3 = radqJ2m(3);

x4 = radqJ2m(4);

x5 = radqJ2m(5);

z = sqrt( (sv(:,1) - x1).^2 + (sv(:,2) - x2).^2 + (sv(:,3) - x3).^2 + (sv(:,4) - x4).^2 + (sv(:,5) - x5).^2 );

%%%%%%%%%%%

i want to understand why, this error occurs and why.

As the documentation states "inline is not recommended. Use Anonymous Functions instead." Change your code to use an anonymous function instead of inline.
