MATLAB: How to create a linspace with a condition

linspaceMATLAB

Hi
I want to create a linspace with a condition for the spacing, so that the spacing has a maximum allowed value. For example, if the spacing gets to high the function creates more points. Is this possible?

Hi,
if you know the maximum allowed spacing you can use:
function result = mySpacing(StartValue,EndValue,maxSpaceValue)
result = linspace(StartValue,EndValue,ceil((EndValue-StartValue)/maxSpaceValue+1)); 
end
This will ensure that the spacing is always smaller or equal to the given argument:
result1 = mySpacing(1,2,0.12)
result1 =
  Columns 1 through 9
    1.0000    1.1111    1.2222    1.3333    1.4444    1.5556    1.6667    1.7778    1.8889
  Column 10
    2.0000
    
    
result2 = mySpacing(0,2,0.15)
result2 =
  Columns 1 through 9
         0    0.1429    0.2857    0.4286    0.5714    0.7143    0.8571    1.0000    1.1429
  Columns 10 through 15
    1.2857    1.4286    1.5714    1.7143    1.8571    2.0000
    
result3 = mySpacing(0,2,0.5)
result3 =
         0    0.5000    1.0000    1.5000    2.0000
