if strcmp(str(1:3), 'Min') == 1
VZ = 1;
end
if strcmp(str(1:3), 'Max') == 1
VZ = -1;
end
VZ
[k l s] = evIII_weibull('param', mevI, sevI, x0, VZ);
VZ
Good afternoon,
the first time I call "VZ" MATLAB gives me the correct value, but after giving it as input for another function MATLAB doens't know the value anymore. Does anyone know how this is possible? Furthermore the function "evIII_weibull" doesn't accept VZ as input (eventhough I have declared it as input in evIII_weibull.m
This is the error message I get:
??? Input argument "VZ" is undefined.
Please help

@madhan ravi
Before VZ was missing an input (required, the function is not varargin)
@Stephen Cobeldick
The if condition is working fine, thank you nevertheless!

If I had been aware that the problem was in evIII_weibull I would of course have provided it. Mercy on beginners :)
