CELL2TABLE Convert cell array to table. T = CELL2TABLE(C) converts the M-by-N cell array C to an M-by-N table T. CELL2TABLE vertically concatenates the contents of the cells in each column of C to create each variable in T, with one exception: if a column of C contains character vectors, then the corresponding variable in T is a cell array of character vectors. T = CELL2TABLE(C, 'PARAM1', VAL1, 'PARAM2', VAL2, ...) specifies optional parameter name/value pairs that determine how the data in C are converted. 'VariableNames' A string array or cell array of character vectors containing variable names for T. The names must be valid MATLAB identifiers, and must be unique. 'RowNames' A string array or cell array of character vectors containing row names for T. The names need not be valid MATLAB identifiers, but must be unique. See also TABLE2CELL, ARRAY2TABLE, STRUCT2TABLE, TABLE. Documentation for cell2table doc cell2table

Hi
Good time
I wrote this code but it gives an error
Please help me
thank you
n=100;
u1=[0,0]';
X1=[-4,-2,0]';
% p=data.PredictionHorizon;
a=0.9;h=0.9;
cp1=1;cp2=1;cp3=1;
% c1=0;c2=0;c3=0;
for j=1:n
c1(j)=(1-(1+a)/j)*cp1;
c2(j)=(1-(1+a)/j)*cp2;
c3(j)=(1-(1+a)/j)*cp3;
cp1=c1(j); cp2=c2(j); cp3=c3(j);
end
% initial conditions setting:
v1(1)=u1(1);
w1(1)=u1(2);
x1(1)=X1(1); y1(1)=X1(2); z1(1)=X1(3);
% calculation of phase portraits /numerical solution/:
for i=2:n
x1(i)=h*cos(z1(i-1))*v1(i-1) - memo(x1, c1, i);
y1(i)=h*sin(z1(i-1))*v1(i-1)-memo(y1, c2, i);
z1(i)=h*w1(i-1)-memo(z1, c3, i) ;
end
%%
function [yo] = memo(r, c, k)
%
temp = 0;
for j=1:k-1
temp = temp + c(j)*r(k-j);
end
yo = temp;
%
%%%%% error
Index exceeds the number of array elements (1).
Error in exocstrstateFcnCT1 (line 28)
x1(i)=h*cos(z1(i-1))*v1(i-1) - memo(x1, c1, i);

You only initialize v1(1) so you have a problem when i = 3 because then you need v1(3-1) -> v1(2)
