According to xticks, then function was introduced in MATLAB R2016b. Your work computer must be at least on version R2016b. On your version, you may need to do something like

 get(hAxes, 'XTick')

to get the current x-ticks for your axes given the handle hAxes, and

 set(hAxes, 'XTick', ...)

to set the current x-ticks. See https://www.mathworks.com/matlabcentral/answers/92565-how-do-i-control-axis-tick-labels-limits-and-axes-tick-locations for details.

Thanks a lot - used the version provided in your link! Got 'XTick' and 'xticks' mixed up while looking for answers.

How about this one sir,

Undefined function or variable 'getWorkArea'.

Error in images.internal.initSize (line 53)
  w = getWorkArea;

Error in imshow (line 309)
      images.internal.initSize(hh,initial_mag/100,is_border_tight)

Error in fcm_seg (line 8)
figure, imshow(Img), title('Original image');

Which MATLAB release are you using?

toolbox/matlab/images/+images/+internal/initSize.m exists from R2014b, but the relevant code line is

wa = images.internal.getWorkArea;

in all of those versions.

In R2011a to R2014a, toolbox/images/imuitools/private/initSize.m has the line

    wa = getWorkArea;

referring to toolbox/images/imuitools/private/getWorkArea.m

For the R2010bSP1 that I happen to have installed, I did not happen to install Image Processing Toolbox

weird I get this error but I have 2017b...

[Walter Roberson]

What shows up for

which -all imshow

I just re-checked R2017b and confirmed that initSize calls upon images.internal.getWorkArea rather than upon getWorkArea
