hello,
I have my data saved in struct format like this
===
MyData=
1x405 struct array with fields
Distance
Binary
Angle
===
my question is: how to save these cell arrays to text files please?

Assuming the fields are scalar, the simplest way is to convert the structure to a table and then use writetable:
writetable(struct2table(MyData), 'somefile.txt')

You must have an old version of matlab then. struct2table has existed since R2013b.

You will have to put the code together yourself to use fprintf as there is no builtin function that can magically save an arbitrary struct to a text file.
I assume you want to use the file outside of Matlab otherwise just saving to a .mat file would be far better.

just takes you to the help page for the function you need to use. There are examples there, but for your own struct you have to work out how to format the text file yourself.

This might do what you want: https://github.com/ewiger/yamlmatlab
It handles nested structures too. For example, if I define a structure like this:
settings.main.medFiltRawImage = 5;
settings.main.doTiledMerge=true;
settings.main.tiledMergeThresh=1.05;
settings.main.secondExpansion=false;
settings.main.defaultThreshSD=7;
settings.mainBin.removeNoise = true;
settings.mainBin.medFiltBW = 5;
settings.mainBin.primaryShape = 'disk';
settings.mainBin.primaryFiltSize = 50;
settings.mainBin.expansionShape = 'square';
settings.mainBin.doExpansion = true;
settings.mainBin.expansionSize = 600;
settings.mainGetBB.minSizeInSqMicrons = 15000;
settings.mergeO.mergeThresh=1.3;
settings.stackStr.rescaleTo=50;
settings.autoThresh.skipMergeNROIThresh=10;
settings.autoThresh.doBinaryExpansion=false;
Then it will be saved to disk with yaml.WriteYaml whereupon it will look like:
main: {medFiltRawImage: 5.0, doTiledMerge: true, tiledMergeThresh: 1.05, secondExpansion: false,
defaultThreshSD: 7.0}
mainBin: {removeNoise: true, medFiltBW: 5.0, primaryShape: disk, primaryFiltSize: 50.0,
expansionShape: square, doExpansion: true, expansionSize: 600.0}
mainGetBB: {minSizeInSqMicrons: 15000.0}
mergeO: {mergeThresh: 1.3}
stackStr: {rescaleTo: 50.0}
autoThresh: {skipMergeNROIThresh: 10.0, doBinaryExpansion: false}
