I try to use fmincon with options being
M = 2;
DC = false;
pulse = load('PCB1.mat');
[pdaeye,th] = pulse2pda(pulse,100000,M,DC);
figure
t = th*SymbolTime*1e12;
plot(t,pdaeye)
legend('Upper PDA eye','Lower PDA eye')
xlabel('ps')
ylabel('V')
title('Peak Distortion Analysis Eye')
grid on
and this is the error I get:
Error using pulse2pda
Expected P to be one of these types:
double, single, uint8, uint16, uint32, uint64, int8, int16, int32, int64
Instead its type was struct.
Error in pulse2pda (line 60)
validateattributes(P,{'numeric'},{'2d','finite','real'},fcnName,'P');
Error in pda001 (line 4)
[pdaeye,th] = pulse2pda(pulse,100000,M,DC);

[pdaeye,th] = pulse2pda(pulse.pulse,100000,M,DC);

Error using pulseRecoverClock (line 98)
Hula hoop clock recovery algorithm of pulse response failed. Pulse response may be corrupted.
Error in serdes.utilities.shiftPulse (line 11)
nclockA = pulseRecoverClock( pulse(:,1), samplesPerSymbol );
Error in pulse2pda (line 86)
[P, cursorNdx]=serdes.utilities.shiftPulse(P,N);
Error in pda001 (line 4)
[pdaeye,th] = pulse2pda(pulse.Vout(:),500,M,DC);
the error it's same....

I assume that you have structs inside the matrix of your .mat file. If you want some element x which is a double or some other type in the struct, you can directly access by S.x If you want entire structure to be converted into array of some type, there is a function called struct2cell which converts the structure into cell array. You can test with the following example:
S.x = linspace(0,2*pi);
S.y = sin(S.x);
C = struct2cell(S)
